This is going to be sick! I’m all about modern efficient designs, but there’s a carnal part of me that gets going when you shove an unnecessary volume of powder behind a moderate weight bullet
7mm Weatherby mag reached the 7 performance sweet spot years ago. There's only so much one can do with 7mm. Further gains are small out of hunting rifles. Deminishing returns? That's why the 28 Nosler is so good. What are the known Wildcat speeds of this 7/378 in a 26-inch barrel? 3400?
I knew an ol' popper, Rip Tom, who built one around 35 yrs ago. Was never able to get to it's potential due to the powders of that time but it would sure be fun to experiment with today. I should add he was a few decades ahead of the current heavy for caliber, long and sleek high B.C. bullet trend. Modified and trued Mauser action with a Smith barrel, probably 30-32 inches that was gain twist rifled to 1 in 8. Timney trigger, blued steel all cradled in a dark exotic hardwood that I wish I could remember the species. I added an ebony forend tip along with flaired grip cap that had a Holly diamond inletted, checkering and a shadow line at the cheeck peice. Dang....I have a helluva case of the wants fight now.
Hold onto your pants! I will be building a 7-378 WBY on an Accumark later this summer. I ordered dies and reamer has to be made. Will be using 30-378 brass and Hammer Bullets 169 HH or 170 HHT.
There is some good data out there on the 7mm-338 lapua and 7mm338 Norma improved. Probably pretty similar, somewhere around 3400 with a 195 in a 28-30” tube.
It’s a wild and extremely inefficient wildcat, but damn, I want to build one so bad. On forums, people have stated that they have almost crested 3600 FPS with a 162 ELDM. Punch that in your ballistic calculator. I put it in at 3550 FPS and at my home elevation of 2200 feet of elevation, it only has 160.4” of drop.
I wonder how those bullets survive that. I assume lower twist rate. Guys are blowing up 180 eldm at slower velocity with 8 twists. Maybe the 162 is more heavily constructed
To be fair I've already replaced my 7mm 378 wildcat build once already. Took 2 years and 1400 rounds to finally show an accuracy inconsistencies in 5 shot groups.
I'd be tempted to get one. I don't think you could get 3400, but 3300 should be easy out of a 26in. Id say any 50bmg powder would be a good idea. Especially the Vihtavuori ones. Id say Nosler is quite unfair to the 7mm ultra mag and probably because they want the 28 Nosler to compare better. I know their 26 Nosler data is pretty warm even for my 6.5x300. It might be cool if they put in a tight twist and someone made as heavy a bullet as possible. I wonder how easy it would be to make an overbore cartridge comparison including a 7x378. Thanks for the interesting information.
Ive gotten 3400 out of my nosler with 165’s. 180’s over 3300 with a 28 but its a hot load. More powder isnt going to help in 24-26” barrels imo and 28-30 is long for a hunting gun but still managable. I dont see a 7-378 being that good but maybe
@orr89rocz so you think at simular preasures, a 7 ultra mag would produce no better velocity than a much smaller cased 7 nosler in a 26? Obviously diminishing returns, but the nosler case isn't that big.
@@wheelchairhillbilly it will but diminished returns. And it likely will end up being finicky. I heard the rum is hard to load for and guys have said the same about the 7-378. My 28 has been abit difficult too
Hell yes, finally. I will be purchasing one upon announcement. Hope they do something fun like a 28" barrel. IF im choosing it would be very similar to a Rem Sendero but with a spiraled 28"barrel. Coming in at 7.75 to 8lbs. Something other than the Accumark because I dont love the Accumark stock.
Thanks for the video man good info for sure. I will have to say you missed the 7mm stw and the 7mm wsm in the line up and also wasn’t there a 7mm weatherby back in the day? Anyways thanks for the video keep up the good work God bless
With a bullet going that fast it's almost a given that you gotta have a sure enough great bullet to stay together. A solid copper like the Barnes or hammer might be the only ones that can stand the heat. Maybe the hornady cx. But probably none of the tipped bullets.
What about a 7-300 Weatherby? Less overbore. Used to be a popular wild cat after listening to Randy Selby (The Real Gunsmith). They already have the 6.5-300. Why not neck it to 7MM? I would be interested to see you talk about this one!
The data for the 7rum seems a bit weak in my mind, but the overbore is a problem with it. I've heard of guys getting a lot more than 3100 out of a 175gr pill. Most are running custom tubes and that is where the untapped potential of the Rum can be found. I wonder if the 7-378 would run into the same issues.
Based on decades of hand loading plus being a 7mm fanboy. I own a 280 Rem and a 7mm Rem Mag and owned others over the years. Having a 378 Wby currently means the bolt is already opened up to the huge dimension of 338 Wby bases. Nosler velocities have always been published on the conservative side. So I expect at least 150 fps faster than the velocity you mentioned. 28” barrel minimum and a good muzzle brake unless you’re nuts lol.
@zebacake4683 I just got a few days ago a Weatherby custom 6.5x300 bee. Talk about fast and flat. Just did breaking in. Now I have 3 factory loads to try and I made some loads shooting 153.5 Bergers. Have a test ladder to find pressure. Going out Thursday to play :)
I believe Weatherby would be better served by focusing efforts on product quality and resolving warranty claims in under two years instead of developing another cartridge with very dubious qualities.
honestly a 7mm RPM would be killer in my mind, bring a 280 AI that doesn't have the issue of everyone arguing about whether the ammo is actually 280 AI or a variation of it :D tho it's not necessarily needed (tho I want it with 25 RPM because why not :D)
That would be an insane round, and probably only drop about 5 mils at 1000 yards. Problem is, i don't wanna have to change my barrel after 3 or 4 hundred rounds
@@tacticalmattfoley True, even with Weatherby cold hammer forging barrels they still don't hold up for very long when your pushing bullets past 3400fps. There are videos ive seen of 6.5-300 barrels getting crazy wear at under 200 rounds

It would be barrel burner definitely, but it's okay, even if was in an experimental situation only, totally a speed demon, with the heaviest and high bc bullets of the 284 diameter, beating the RUM and STW for sure, let's see how it does, with the right twist rate and tube length, 338-378 Wby loves burning Ramshot LRT by the way
A 7mm-378 would be an awesome cartridge. It would most definitely be a barrel burner, but who buys a Corvette and worries about tire life? A 26 inch barrel would certainly be too short, but for a hunting rifle a 30 inch one would be too long. I would think that if Weatherby brought this cartridge out, it would be wise to follow John lazzarone‘s path and use a 27 or 28 inch barrel. And speaking of John, that brings up a question. Would Weatherby actually introduce a cartridge that at best would be second place to his 7.21 Firebird? I know that Lazzaroni is a proprietary company, but Weatherby is certainly more proprietary that main stream themselves. Just food for thought 🤷🏼♂️
Yea, if you think the .300 RUM and the 7mm RUM are overbore just wait for the 7mm-378. I have 26” barrels on my .300 RUM and my 7mm RUM, for the 7mm-378 you’re going to need a 28”-30” barrel.
7mm STW is really the most you’re going to get out of a 7mm in a 26” barrel. Frankly if a 7mm-378 were to be made, it would need a 30” barrel to burn all of that powder.
Weatherby should bring out the 7mm-300 that is and has been used by wildcatters. It would be in the same case as the 6.5-300 and the 300 in the same manner as the .257, .270 and the 7mm are using the same case. But they probably bring out the other just to say they have the “superbest” 7mm instead of what is actually needed.
My custom 7 rum with a 180 berger gets 3300fps with a 28 inch hart barrel i have both 30-378 and a custom 338378wby and like u said a 7-378 gonna need a 30 inch barrel
@@ReloadingWeatherby I don’t know I’ve seen a 6.5-300 go from sub moa to 2” groupings at 100 in just under 250 rounds we bore scoped it and found a significantly worn out barrel. I can’t imagine the 7mm-378 would be any better . Definitely going to be a high performance hot rod cartridge.
This round will suffer from the same thing the 7 mm RUM does, can't burn the powder efficiently and will never get the velocity you are looking at, without a 30 or 32 inch barrel. Secondly the mag is to short to load the longer bullets. If they were smart maybe a 7-300 Norma. 7mm wby mag is the best 7 mm out there, just put a fast twist barrel on it.
Wow. Incredible numbers. I know it’s human nature to go faster and faster.! But really is an extra 400 to 500 FPS. Worth the almost double the recoil?? I absolutely love my 7rem mag I’ve had it for 40 years and every big game animal I shot at ended up in my freezer. But in saying this if there was a say 195 or 200 gr partition that you load in the 7mm -378 now you’d really have a top North American do all round. Just my two cents. Cheers
7mm-378 with a 120 or 140 TTSX would be like the full r*tard version of the 130 in the 300 Weatherby! How much velocity? All of it. Barrel life? Don’t need that where we’re going! And on a more serious note, a 7mm RPM with a fast twist and performance close to or equivalent to a 28 Nosler with better efficiency and improved barrel life could be a home run.
I loaded my rum up yesterday 3300. Is a cake walk for a 175 😂 and a 26 inch barrel with no pressure signs 3400 fps wouldn't be hard I sling 165 over 3500 fps u can actually get 3300 fps out of 7 stw kinda like your 300 push it with right powder and hold on
No need for the 7 mm - 378 with plenty of flat shooting 6.5 and 7 mm calibers out there. Any advantage will be past 500 yards and most hunters do not shoot at those distances. It is not ethical anyway, too much risk of a bad shot wounding an animal rather than a human dispatch.
My only fear with this cartridge is it’s going to encourage more long range hunting😔 I love to target shoot but this see how far we can shoot at a game animal is such a big mistake! First it just encourage the anti hunters as well and the democrats but hunting is turning into target shooting not hunting which is a sad state for what’s going to happen to the game animals being wounded🤔😳
That cartridge will be ridiculous. Basically the ThrustSSC of the cartridge world - sleek, not lasting long, expensive and physics will kick your behind 😂.
Well hell Weatherby since you are obviously having size issues why don't you just make a end everything and develop a 30-460 the fastest of the fastest 30 caliber chambered in the 460 Weatherby 😅😅😅😅🎉🎉🎉🎉🎉😂😂😂😂

The barrel will be half worn out by the time you have it sighted in🤔😳
haha maybe
It'll close to 3500 fps
All for 149.99 a box
Probably more
No need for the 7 mm - 378 with plenty of flat shooting 6.5 and 7 mm calibers out there. Any advantage will be past 500 yards and most hunters do not shoot at those distances. It is not ethical anyway, too much risk of a bad shot wounding an animal rather than a human dispatch.
Please compare the 7-378 with a 175 gr bullet with a 30-378 with a 200 gr and you will see there is no need for the 7-378 !……
Zero barrel life
My only fear with this cartridge is it’s going to encourage more long range hunting😔 I love to target shoot but this see how far we can shoot at a game animal is such a big mistake! First it just encourage the anti hunters as well and the democrats but hunting is turning into target shooting not hunting which is a sad state for what’s going to happen to the game animals being wounded🤔😳
Kirby Allen has already bested this 7/378 weatherby. Just saying
165 gr 4100fps
That cartridge will be ridiculous. Basically the ThrustSSC of the cartridge world - sleek, not lasting long, expensive and physics will kick your behind 😂.
Horse power race with guns these days . So some dude can be in camp bragging how fast his gun is .
We love speed
Well hell Weatherby since you are obviously having size issues why don't you just make a end everything and develop a 30-460 the fastest of the fastest 30 caliber chambered in the 460 Weatherby 😅😅😅😅🎉🎉🎉🎉🎉😂😂😂😂
They already have it. It's called the 30-378.
Won’t be practical at all. 28 Nosler is already a barrel burner
Thanks for watching!
Dang ! People are ignorant. Like voting for Joe Biden. Corn Pop was a bad dude😂
Huh?
And you got there from here...How?
@billbennett9537 Easy ! 7mm-378 is dumb . Not practical.
@@jaybailleaux630 Your comments certainly do not show any intelligence from you.
@@billbennett9537 OH....WELL.....We need not get personal. It happens.
7stw
Sweet another useless cartridge that will cost too much and only be around a few years
