338 Win Mag vs 375 H&H: Surprising Results On Steel
Вставка
- Опубліковано 9 лют 2025
- In today's video, we will be comparing the performance of the 338 Winchester Magnum and the 375 H&H Magnum on mild steel. These are two absolute power houses, so I hope you enjoy. Testing was setup at 50 yards using A529 gr 55 mild steel along with steel sled v3. Thanks for watching!
Steel Sled 4.0 is coming.
Testing: 2:32

Both are great CCW caliber choices!
Pretty easy to hide for sure, long barrels and all

Both great calibers, no losers here.
Read once that the 338 was more that capable of taking any living thing on the American continent. While the 375 was capable of killing anything in the rest of the world.
I lived Alaska for 40 years and hunted big game there for 35+ years. I did a lot of research comparing both of these cartridges prior to making a purchase; the .375HH has 10% more energy on paper and considerably more $ to shoot, it also is easier in the felt recoil dept. IMO. I opted for the .338WM and was nothing but impressed every time I hit my mark, and fortunately I am not recoil shy, many cannot deal with the recoil beyond the great .30-06' (which I hunted often with as well). The .375HH has been romanticized for sure, the .338WM, not so much. I agree that one cannot go wrong with either choice, but I have a soft spot for, and tremendous confidence in the .338WM.
Words from the wise, take care.
I totally agree with you on the "easier in the felt recoil dept". I've always been pleasantly surprised at how my 338 WM was more of a push than a kick or buck. So, many years ago when I decided to pick one rifle for both deer sized game, and elk/moose/bear/grouse sized game, I quickly realized I already owned a rifle that fit the bill. I hand load, so I can down load the 338 for deer, and up load it for elk and above. Thanks for your post.
375 has more energy out to about 200yds, 338 takes over after that.
I think a lot of the African countries require a minimum caliber of .375 because a lot of foreign hunters can’t shoot all that well. In the hands of a decent shooter, there’s a minimal difference in performance when appropriate bullets are used.
I have .375 Sako myself. Absolute work of art gun. But honestly when it comes to recoil my old budget Mossberg Ulti Mag in 3.5 mag kicks just as hard as .50 cal.
I lived and worked in Ethiopia from 1977 to 1984. Working on a rural project I had access to some rural wart hog shooting. I shot a BRNO ZKK602 in 375HH. I only weighed 70 odd kg but had no problems with recoil providing I held the rifle close and tight. It's more of a push than a hammer.
It shot very flat at the ranges I shot, 50 to 100mt with 250 to 300gr ammo.
Upon request of the wildlife authority and in company with a professional hunter and game scouts I shot a hippo at 30mt. The 300gr solid went through the left shoulder, across the chest and stopped under the skin on the right side.
The animal dropped immediately.
Food for thought... depth is one measure. Volume of steel removed from plate is another. If you truly want to declare a comparison winner I would suggest measuring not only depth as you have done here but also a water volumetric measure as well after grinding flat. Because it would appear that 375H&H removed much more overall steel.
Anyhow it would be an addition dimension that would make it more interesting I believe.
Thanks for the comparison!
The other issue with measuring depth is the steel plates are deforming across the plate by small amounts with each impact, with the most deformation being near the holes and being inherently unequal as caused by unequal cartridges. So accurate measurements are not possible anymore, even with his commendable care to file all craters level. I love this channel though. And he knows he is not being scientific but practical.
I was thinking the same thing as I watched this vid. While the holes looked similar in deformation of surface and depth of penetration, it was clear the 375 was doing more "work", AKA bigger hole.
Good contribution 👍
Guides in Alaska use the .338 Winchester Magnum as a "Back-up" or "Sure to stop 'em" gun when they take clients out for those really BIG Kodiak Bears 🐻.
I'd hate to get hit with either!
THANKS FOR AN EXCELLENT DEMONSTRATION!
.375 ouch & ouch is still one of the best performers available, since 1912.
It's also the yardstick for all other dangerous game cartridges and the minimum you can use in several African countries.
Nonsense, I've used 6.5 Grendel on Cape buffalo and hippos many times. It's all about shot placement my friend, they drop like flies with my trustee Grendel, but a 20in barrel minimum is required.
@@actionjksnI think he means, most game farms only allow the minimum of a 375 for dangerous game and that is the general rule of thumb in S Africa at least and probably a number of other Southern African countries.
It just ups the likeliness of a kill. It sucks having the trackers have to track an injured animal down when it's an avoidable risk especially when it comes to things like Cape buffalo.
Correct, it's actually the LAW in South Africa 375 min for dangerous game, rightfully so I'm assuming grendel guy was not hunting here.
I hunt hogs regularly with a 375 H&H. The 300 grain dangerous game solid penetrates a bit more than the 270 grain loads. I know it will knock down 2 big hogs and then pass completely through a 12" diameter pine tree. I also know it will easily pass through an AR500 steel 3/8" target. Try that load on the 3/4" plate.
Golly, what kinda hogs are you hunting that you prefer 375 H&H😂
the kind that will charge a side by side with no fear and rip your legs off if given the chance.@@adamowen366
You need a softer projectile mate
@@adamowen366 A wee bit overkill perhaps? 😆
Dangerous Game solids on hogs. Lololol.
Had a Kodiak island trip planned. A Browning BAR in .338 Win Mag was my choice.
I am a BAR fan also ,'06 and .338 are all you need...shot placement is the deciding factor..
Quick action, no drama, and a touch of dry humor. We love your style man. Keep up the great work
Seconded. Great content, consistently.
Awesome video man. I am partial to the H&H but the .338 kicks ass too. Thanks for doing this video. Know it isn't cheap.
The .375 left visibly larger holes through the thinner plates & a wider crater in the 3/4” plate, I imagine that the volume of the crater was greater for the .375 than for the .338 - & this would result in greater killing ability in a hunting situation.
I'm not sure which is more impressive. Watching both calibers punching holes in steel or seeing you absorb the recoil from those behemoths.
Lol, the recoil is no joke from the bench
Those are like nerf guns to Kentucky Ballistics, which is also very impressive
@Boaris_Johnson KB is insane with the punishment he puts himself through. When (if) he gets older, he's going to have severe arthritis.
.338 Win Mag is no joke!
Impressive. Very good comparison. 338 did quite will against the bigger brother. Well done. Thank you.
I've owned and reloaded for both of those big boy cartridges. Interesting and well done.
Love the .375 HH Mag, it has a great history, and I would love to see you trying the Dangerous Game Solids, to see how they perform.
A .338 and 250 gr has a higher sectional density than a .375 and 270 gr. Would be interesting to see results with FMJ bullets or even solids.
Thanks 🍌 ballistics I always wanted to see these two stacked up, they always looked similar on paper but as we all know paper can sometimes be deceiving!
I really enjoy your videos, man 👍
Be brilliant to see a 458 win mags performance on 3/ steel. Ever since I saw that rifle used to hunt the bad guy in dirty Harry on the roof tops I have wondered what it's outright performance was.
Great videos, keep them coming !!
I do have to say, that’s pretty impressive for soft point bullets. I wonder how the performance would differ if using Barnes TSX’s or a premium bullet like the Nosler Partition?
I think the partitions would do really well. From my experience, solid copper bullets like the TSXs are not very effective on steel for some reason
From reloading, I found that TSX bullets are softer than partitions. Makes you wonder if Nosler uses a copper alloy.
When I saw this video, I thought about the old Winchester Fail-Safe bullets. Like a partition but with a steel cup in the bullet to protect the rear lead section of the bullet. Those were pretty cool…haven’t seen them around for about 16 years.
I have some solid brass spitzers that i use for target shooting in the 375. Would have been interesting to see how they performed on something like this
Lead core rifle bullets actually work better on steel than copper or mild steel ones. Don't know exactly why but it's a pretty reliable observation. Would genuinely be curious about brass solids, as unfortunately most videos featuring brass projectiles are using lower velocity, very heavy bullets. .416 Rigby brass is already impressive at 2400 fps, would love to see even higher velocities.
@KyussTheWalkingWorm…lead is very soft, but it is very dense. That’s the only thing I can think of.
A solid brass bullet would be interesting to see. That, or maybe hard-cast lead alloy bullets.
Would be great to see you do:
.22 WMR vs 5.7x28mm
.30 Super Carry vs 5.7x28mm
.30 Carbine vs 5.7x28mm
.30 Carbine vs .45 Winchester Magnum
.30 Carbine vs .45 Colt
When you refer to the .338 win mag gets referenced as the small boy you know your shoulder is going to hate you in short order lol, impressive though, good vid.
Would be interesting to see a rematch using solids.
I love the video shooting those big bullets at the Steel Plate’s. Yeah any Steel Plate that’s getting towards one inch or more becomes too solid to penetrate but you haven’t tried a 50 BMG on the plates. That would be interesting of how much Steel you could penetrate that probably will get through the 3/4 inch and might nearly go through the one inch plate
Makes me want one.. but then I definitely don't want the recoil or the expense of the ammo!
I'll stick with my 358 Winchester! It's my dedicated black bear rifle and occasionally whitetail deer 😊
“Running” has to be the most needlessly overused word in the outdoor sporting world right now. “For my supper, I’m running a cheeseburger and fries next to a large soda.”
You sir are a badass. Thank you so much for doing this
During WW1, German troops started wearing crude body armor which defeated the British .303 rounds, so a plucky chap was like ‘Right, let’s get that new .375 rifle o’er here,’ and wouldn’t you know it there was ventilated Germans.
They also used 577 Nitro Express as well. It was said to cut through the thickest of German armor like butter.
One major flaw my friend... You did not take sectional density of the bullets into consideration. Higher sectional density means more penetration. The 250 grain of the 338 win mag has a sectional density of 0.313 while the 270 grain of the 375h&h has a sectional density of 0.274 .
Much lower sectional density and hence much lower bullet penetration for the 375h&h. Had you used a 300 grain bullet in 375h&h it would have out penetrated the 338 win mag.
In conclusion if you use a bigger bore, you have to match the sectional density of the bullets in order to perform a fair test.
Exactly my thinking while watching this video. This test was Apples vs Oranges.
Great video. Thank you.
Thank you, I appreciate your work. You make an excellent contribution!
Nice! Do you have a sweet spreadsheet already going to compare the depth of penetration for each plate with every caliber tested so far and in one place? If so let's see a killer screenshot 🤘
I do not, but I’ll have to see if I have time to make one
I shoot and love both of these calibers. Some of the best rifles around for dangerous game!
There is something about Winchesters magnum calibres that are just plain nasty. That goes for the 300WM, 338WM and the 458WM. Some experts say it's because of the case design, or trying to make the projectiles go unnecessarily fast. Others say Winchester sells the calibres in rifles that are too light. I think its all these. A magnum length action is a bit heavier at the point of balance. Whats this obsession with shorter actions? Americans seem to get hung up on this so called feature. Maybe its cost as well. But lets face it, the difference between mass produced American rifles and European ones are that the latter are simply nicer to shoot because they have less recoil.
The 375 H&H Magnum in a 10 lb rifle is a joy to shoot and the long, sleek magnum case feeds really smoothly and reliably, and the powder burns more gradually. Its the same with the 338 Lapua Magnum vs the 338WM for exactly the same reason.
Great content! thanks
Yep with only 75 feet per second difference, the other two factors are key: Those are sectional density and hardness of projectile. The .338 had a sectional density of .313 while the .375” 270 grain had an SD of .274. So yeah that’s a big difference in SD!!!
I think the .375 could beat it with a solid brass? It’s velocity hardness of material/construction and sectional density. Abd those are in order of importance. However if you lack one you won’t have much of any penetration. I think 5.56 demonstrates this the best. It has 3,000 FOPS but over penetrates less than many pistols. The reason is high velocity and low SD with average bullet construction results in minimal penetration and excellent terminal effects. Lower density material seems to favor SD over velocity and hardness on metals like steel.
I wish this whole balance of velocity hardness and SD would be studied by someone!!!
I don’t understand why he talks about frontal area without listing the SD??? SD is critical to penetration!!!! Use a calculator like I do!!!
Anyways gutsy content if please start listing the SD it make comparisons easy. For instance a 120 grain 6.5 has about the same SD as 165 grain .308. This becomes a 140 grain 6.5 equalling about 190 grain .308. Such information would help explain your videos and greatly help your data collection.
What formula are you using to calculate SD?
@@jimgordon3206 Sectional density: [bullet weight 7000/grains] / [bullet diameter²].
7000 grains is 1 lb weight.
Example: [270/7000] / [.375²].
Or 0.03857 / 0.140625 = .274
Ooookay, start with the very first bracket mark and slow down your explanation.!
I made a sand bag out of a piece of denim jeans. Put between the buttstock and shoulder tames my .338 off the bench by a significant amount.
simply buy a past pad or better yet a lead sled for sighting in,
The .338 has a higher sectional density.
Agree. He should have used 300 grain for the .375.
How big of a different is there on the 300 win mag and 338 win mag? And could you do a video on 6.5x55 swede and the 6.5 creedmore?. Love your videos and have a good day from sweden 👍😃
We may just have to see. I really appreciate it!
American factory ammo will kill the performance of the x 55
I picked up a 6.5 Creedmore based on its ballistic closeness to the 6.5x55 and lack of funds for a new 6.5x55.
I have taken everything on this continent with the 338 with no issues. Premium bullets ALWAYS. I Did use the 375 once for moose. Very satisfactory but the 338 would have done very well I am sure. 👍👍

I'd love to see what a 300gr Brass solid from the .375 H&H would do to the 3/4 steel
I’d like to see you do a three way comparison between 35 Whelen, 9.3x62 Mauser, and the 375 H&H
As one other guy suggested, a volumetric water measurement would be a great addition to the testing!
Do you have a video of the 338 win mag vs the 300 win mag?THANKS
You have the best videos and accurate God Bless you finally someone that shows the truth and no BS thanks 🙏 😊
I’ve hunted with a .375 H&H for 30 years. I’ve killed a lot of deer with it. Some, out to 500 yards, (laser ranged). I hand load for all my pew pews. It loves maxed IMR 3031 and 300 gr game king BT.
Did you ever think of using a 200 gr bullet? What was the lightest bullet you have used for shooting/hunting with your 375H&H. I am kicking around 200 gr. I did find some 235 factory loads that I am interested in. I'm just investigating at this point.
@@billyhancock7851 Barnes used to make a TSX in 180 gr but I can’t find them anymore. Personally, I use the 300 gr because the rifle shoots them better than any other weight. I’d use what your rifle likes the best. If you’re going to Africa, I’d use the heavier weight bullets, especially the bonded, partitioned ones. If you’re going after American game, anything expending will work fine.
Buffalo Bore is using the 235gr Barnes tax and Hendershots Sporting Goods Extreme custom Ammo is also using 235 Barnes tax bullets. I don't know very much about them but . contemplating using the bullets. Just studying to see if there is a good great bc, long range/short range deer to moose cartridge. Would probably do the 300 for bear, I am wondering if I reloaded the 200gr "handgun" bullet would it work well or destruct on contact. Just studying options 🤔
@@billyhancock7851 handgun bullets were never designed for the velocity nor the energy generated by rifles. They might break up in the air or blow apart on impact. For moose, I’d use a partition or tsx bullets. If your looking for a good BC, the game king boat tail is best or the accubond.
The 375H&H has had so many pretenders try to take the throne... Still King of the mediums.
Adding a sandbag behind the bipod might help keeping the rifle from jumping and mitigate some of that recoil.
It would be neat to see a 340Weatherby next to them. Your shoulder may be sore after shooting it from a bench though.
I've never heard of either caliber. Great video. ❤
Extremely scientific. 🧐 At least very entertaining. Keep up the great work.
I really appreciate it!
@@Peter-nm1ps - I visit gun and ammo stores weekly. You are likely correct as I'm no veteran gun-ologist. But I've never seen ammo for either. Maybe I just missed it.
You’ve got to be the first person who hasn’t heard of the H&H. I have a .375 Ultra Mag. Kinda wishing I bought the .375 H&H because it has quite a bit less recoil.
@@stephenparchewski1998 - No, I'm the 17th.
@wyomarine6341You guys in the lower 48, or hell even below the Arctic circle like to hunt with too much horsepower.😅
Great videos man!
Cool seeing another 375hh weatherby vanguard. Great price for an accurate gun
Do they make fmj for either of these calibers? Oh and try shooting a .45-70 with a brass buttplate and hot loads from a bench- that about killed me.
I believe that they make them for both, but the 375s are a rounded nose instead of the pointed 338s
Pretty sweet comparison,
Was there much difference in felt recoil between the two rifles?
homie gotta sing the chocolate rain song hahaha
but for real good no BS video. keep em coming
Would like to have seen the .338 Lapua in the mix....

At 250gr the .338 had higher sectional density. Use a similar SD in the .375 and it might penetrate better.
But then velocity drops off.
@@stanpotter7764 May not matter. Also factor in momentum.
@@exothermal.sprocket Momentum is pretty much meaningless when in comes to steel. It is more of a factor in hunting.
@@stanpotter7764 Explain momentum.
@@exothermal.sprocket Dude, speed kills steel, everbody knows that. Momentum will move the plate more but KE puts holes in steel.

Great channel. Thank you
I shoot both , 375 Weaterby in pre 64 and 338 Wm in Howa and Brno action . 375 With 300r Noslers , 338 s with Perigrine 250gr and Aframe 250 gr . On a recent Cape buffalo hunt , the hunter anchored the animal with the 375 . As backup shot the perigrine penetrated both shoulders , exiting the far side . Lot of open eyes .
Please start listing the SD of every bullet? This this is absolutely critical for penetration. If would very helpful with comparing calibers. Such as a 160 grain 6.5 is nearly the exact same as a 220 grain .308. So I think it would help make your data more thorough?
I’ll try to add the SD of the bullets into the videos. Thanks for the idea
@@bananaballistics Thanks for the content!!!
Why aren't you checking the craters for volume instead of depth
I like watching the heavy hitters , bell is Lit
Would be interested to see a NERA set up target.
Should compare the 338 Lapua to them. lol 👍
Need 15 grain more powder to gain 150 ft/s , never made sense to me in a hunting rifle .
I own rifles in both, so this was very interesting for me! Thanks for another awesome video! 🤜🏻🤛🏻
You should test the 270wsm on these plates. They say speed beats armor and the 270WSM has a ton of speed specially if you use the lighter loads. I have one you can borrow if you need it.
Great video!! But not very fair for the legendary cartridge. At least the 300gr 375H&H would put a much fairer fight against the 250gr 338wm in regards of Sectional Density 0:37
I would be interested to see how the 9.3x62 compares to the 338 Win mag.
Awesome video, dude. Could you try the .375 Ruger, vs .375 H&H. A lot of folks say the the .375 Ruger, although a little shorter than the .375 H&H, it is said to be more powerful, as it’s the upgraded version, made to fit standard length chambers.
Wasn't .375 Ruger a .308 necked up? I remember a .338-08 awhile back that was a .308 necked up to .338.

Note: this is a comment addressing numerous posts from Banana Ballistics not just this one.
Don't mean to be critical but you seem to want to pass yourself off as a scientific evaluator. One of the things I would do to level the field is to compare FMJ with FMJ and Steel Penetrator AKA "Armor Piercing" to one another. Why you would want to see the effects of a hollow point or soft point ammo on steel is beyond me. Why you would use "Military Ammo" on animals or ballistic jell is also beyond me. I'm an Aviator and would compare STOL with STOL, Transport with Transport and Fighters with Fighters. Never would I compare one with the other because they are different devices with different missions. I know you want to publish but lets keep it on the map. You are fun to listen to but you're more of a performer than an engineer. I've seen your latest sled 4.0... wow using a cast iron vice hmmmm? My advice is to cut four reliefs two in the top and two in the bottom edges of your plates to accommodate some baling wire and strap them to the 2.0 sled or whatever you have lying around your shop. You could have three sleds with preloaded plates ready to go; even tack welded if you please but keep clear of the current engineering, NOT WORKING. Having them tacked to the frame wouldn't allow the plate to bend and possibly change the penetration results to something resembling real plate. Don't know how far you are firing from but it seems that missing by 5 inches or more is routine with you; I suggest that all of your sleds would suffer from this practice. Maybe zero the gun when you are doing your velocity data, just a thought. Lastly, your steel barrier is kind of amusing, because the only part of your body that could possibly be injured by deflecting projectiles is exposed (face eyes) while the rest of your non critical mass is protected, shows more than a little hindsight, at least you are wearing eye protection. I shot steel IPPSC for years with a 45 ACP 1911 and it was routine that some of the audience could get pelted with lead, even my own wife. It is imperative to wear eye protection always and as a side note, nobody ever got killed or seriously injured during my time there. You'll figure it out, best of luck with your project. P.S. just cause I'm critical doesn't mean I don't like your work. I'm Subscribed as of now.

I miss version 2 or steel sled 2.0. It goes by both names. Maybe a drop in plate style sled. I’ll work on it.
What about .375 ruger
It's about the same, but around 100 feet per second faster. It's a very impressive round.
I wonder if the .375 H&H using a dangerous game solid bullet would go through the 3/4” plate?
Retest?
you need far more subs
During WWI the Brits used the .375 H&H with solids to punch holes through the steel plates that the Germans were using to protect their machine gunners
Well what ever your destroying it just sounds more elliquent when you say nailed it with the safari 375 H+H. BTW I have one it is awesome lol.
Since the magnets didn't work out so well, I'm betting you could fabricate a bracket that would fit in the carry handle slot that would also just slightly overlap the top edge of the target plates. I'm thinking something sort-of C-channel in cross-section, sized to your thickest plate, with a square hole in the top that you could emplace a simple wedge to adjust for the different thickness plates. Maybe make the front of the bracket just slightly wider than your plates, and add a pair of "ears" to keep the plate from left and right too much.
Have you tested 7mm win mag? I’d love to see that test.
It would of been nice to try the 338 lapua against the old H&H man that H&H would be my dream gun in a lever action. Thanks
Wonder about 300 win mag vs. 338 win mag
That would be a good one
Food for thought: One issue with measuring depth is the steel plates are deforming across the plate by small amounts with each impact, with the most deformation being near the holes and being inherently unequal as caused by unequal cartridges. So accurate measurements are not possible anymore, even with his commendable care to file all craters level. I love this channel though. And he knows he is not being scientific but practical.
When it comes to punching holes thru steel plate sectional densities go out the window, velocity becomes king for penetration, the 338 at 2650fps is on the slow side by about 100fps, while the 375 was pretty much at max velocities, years ago our local rod&gun club had a member that was chief engineer at out local saw mill, all lumber was shipped out by rail, the club started playing with shooting steel plates and the web of railroad rail supplied by the engineer, a 240 weatherby was the king shooting 70 gr bullets at about 3900fps if a recall correctly, it was followed by the 220 swift, I don’t recall bullet weight for the swift, they ran penetration test shooting a sluce box full of wet saw dust, when somewhat equal velocities were being run, the higher sectional density slugs penetrated the deepest,
What is the difference between a .3e38 win mag and a .338 Lapua?
Depth is the only thing you considered. The area of the hole for the .375 H&H is lager, and more metal by weight was blow away. I will always prefer the .375 as ammo is easier to find
since way more rifles are chambered for it.
I wanna see the same test with brass solids.
Military 7.62mm is about 828 metres per second (around 2700 +fps)
The sectional density of the .338 was higher than that for the .375, so the .338 should have penetrated more deeply - it had higher mass per square inch of area hitting the plate. It does make one wish there was a 5/8" plate available, doesn't it?
416 Rigby?
Someone needs to sponsor you with their ammo . . . works for Hickok 45
Great video…
A 375 using 350 or 380 grain bullets puts it into the 400's class for Buffalo, there is a reason its seen as the minimum for dangerous game in many African countries
