- I try to get 3000 fps with the 165 Accubond Long Range bullet, out of my 270 Winchester Short Magnum using MagPro, H1000, and H4831SC.

Love this. My dad has had my mom hunting elk on our ranch in eastern Oregon with a .243 for years.
I’m planning on buying my mom a Tikka .270 WSM and have been researching a 160gr loads.
Was thinking the Tikka T3x Veil with the muzzle break.
@@ryanlogan2911 great choice
IMR 7828 SSC and RL-22 will get you 3000 FPS. Good luck finding any
I am retired and have all the time in the world and I don’t ever see any and when I do now it’s getting close to if not over $70. A pound 🤔😳 not counting shipping and hazarded material
Find any what? 😂🤣😂🤣
I appreciate it, you think R22 would get more than Magpro?
@@hopefulballistics Possibly... but every rifle is different
Thank you for sharing your time and experience with us!
Thanks for watching!
The elusive 3000 ft/s 😁. Massively enjoyed the video though, thx!
As per the calcs I shared last time, you should have another 1.5 grain on the H4831 before even hitting spec pressure. But that won’t get you there.
The IMR 7828 should be your best hope, unless you can get your hands on the Vihtavouri
Thanks, I appreciate it!
I hope your next experiments involve the 155 LRX in the WSM! That’s the one I’m most interested in, stability wise.
I almost bought some, but I’m not sure they would stabilize. I still might and make a video out of it.
another great video!!! I like your real world, no guff, actual "live" results. It is all about finding what you gun likes and dislikes. My 7 rem mag does not do well with h1000 and 162 gr eldx, but when i use h4831, I get great accuracy. Keep up the good work and like seeing the subscriber number getting higher!!
The 7 rem mag is a great cartridge and not going anywhere soon! I just bought 5 more of them in the last 2 months and that’s not counting the ones in the shop for new barrels and triggers🙌
I appreciate it!
In a short action, the 270 WSM is getting similar velocities to what a 280 AI will get with a 165g bullet. Impressed.
Thanks!
Love your approach and efforts to help others. Ladders are pretty basic but you present well with a chrono vs others who convey fps on a box on UA-cam
I appreciate the comment. And I’m having fun doing it, lol.
IMR 7828 and the IMR 4831 would be great powders for this caliber and bullet combo
Thanks. You think the IMR4831 would do better than the H4831SC?
@hopefulballistics yup. I've tried both of them and I'm getting better velocity from the IMR 4831.
In my little experience. The h1000, retumbo needs at least 24 inch barrel to get the velocity also a heavier bullet.
Ya that’s the only problem with loading the WSM’s hot they only come in 23” barrels from most manufactures do you have to replace the barrel if you want anything longer otherwise you will see your powder flaming out the barrel with no benefit. There is a lot of powders that cross over to match another powder but you will still have to get a faster twist barrel for the heavier bullets anyway from what I have found in my short 60+ years of reloading 😳
@@edwardabrams4972 good to know. I have only been doing it on my own for 2 years now but had help for 12 years. I tried retumbo in my 300 win mag 24 inch barrel. Even with low powder amount I still had lots of powder out the end of my muzzle. I wounded if that powder needs a 26 inch barrel? I traded the retumbo for h 1000 because of that issue.
Makes sense
Mine is 24 inches
I just got 2929fps with my 6.8 western (24”) with 175gr STGK and H1000. I can let you know what I get with the 165 with H4831SC soon. How is your powder capacity in your 270WSM when you seat these longer bullets? Maybe it’s reducing how much powder you can fit when compared to the 6.8 western neck design which allows the bullet to be seated further out to assist in capacity.
Maybe, but Magpro fills it the most, and I wouldn’t say it’s compressed.
Cool video mate. Nothing wrong with 2950 at all! Would have some impressive numbers ballistically down range. Thanks for the content👍🏻
@@MattW-wr7th thanks for watching!
Just updated previous video comments with H1000 & H4831SC.... Another great video! Keep them coming!
Thanks for watching!
@@hopefulballistics Just did another round with Norma Brass, H1000, WLR & Nosler 150g BT. 3119 & 3144 at 67.0g. did a 2 shot ladder test.
@@johnmcveigh6133 nice
That MagPro is the sweet sauce for 270 WSM. I've only had one for a few months, but every load I've developed with it has been a keeper. I haven't had that kind of immediate result from any powder/bullet combination with any of the rifles in my collection or handguns, for that matter.
That’s been my experience too!
Reloder 26 will get you there no problem but it's very hard to find.
Yeah, it’s unobtainable right now
6.8 Western, average velocity out my gun 2966 fps. factory ammo. Mmmm. Sell that thing! Buy a 6.8 Western!😅 Seriously, great video!
You better buy all the 6.8 brass you can because it’s DOA cartridge😳 I have been collecting reloading and hunting for 60+ years and have seen many many cartridges come and go and the 6.8 is on life support right now😳😱
@@edwardabrams4972 ADG brass is on the way! I'm doing CPR right now, I'm still seeing signs of life! #savethe6.8western!
Yeah I saw you short. Lol
How 270wsm has more case capacity 😂
Ramshot Hunter seems to be a good powder for heavy for bullet loads. Worth a shot if you can find some
Thanks
Berger has load data for their 170 eol for 270 wsm and retumbo and n570 have the best velocity’s
Good to know, thanks
@@hopefulballisticsdid you ever do a part 2 on the cx bullet for 270 wsm
Might be the throat of the 270wsm you’d think more case space is better but maybe seating the bullet deeper takes more powder space then you think
I would would like to see you do some tests with the light weight barnes 95/ 110 ttsx to see what velocities you can get
I'll second the vote for imr 7828 . I don't have any experience with R 22 but don't understand how that will work.
I know a lot of people swear by it. But you can't get it! That is the real problem. You have to go with what is out there.
I'm about to try some of the magnum powders form Vihtavuori because they do seem to be available a little more often. Imr 4831 I have experience with and I didn't think it would work. However it does seem to shoot well.
@@JJ-qy8xu it might well be. I have a few more powders I’m going to try.
H1000 is great for stability and consistency, rarely is it a speed powder.
I appreciate it
I just looked quickly on the Hodgdon website and they list Magpro as one of the fastest for the 160 Nosler Part. It's only a little faster than what you get with the 165 so I think you've reached as fast as you can safely. All the other powders they list are slower. Winchester StaBALL HD lists 3050 as the top speed for the 160 Nosler partition so you might be able to get 50 fps more than with MagPro.
Good information, thanks!
I'ts been interesting watching your results with this. I know that it's hard finding brass for the 270 WSM and components are not cheap. But there is one powder definitely worth trying if you were to entertain trying anything else and that is Vihtavuori N570. I saw on the Long Range Hunting forum where a guy used 70.5 grains with the Berger 170 EOL and got 2967 from a 24 inch barrel in a 270WSM, and that charge weight resulted in a 103% case fill. If you used a hotter primer like the fed 215 or wlrm with that powder I believe you could reach 3000 with that ABLR - might have to bump it up to 71 grains. The good part about using a slower burning powder like this is you probably won't get excessive pressure. I have read several accounts of people using N570 in the 7SAUM with heavy bullets and getting good results, and the 270 WSM holds a fair bit more powder than that. Plus, you can actually buy N570 right now. It's usually harder to find but there are several places I've checked recently that had it in stock.
I need to get some N570.
Another good video!
Thank you Tom!
I have a 270WSM also. Try changing primers with your Max charge with Magpro. You might hit the 3000fps. My 270WSM really likes magpro. good luck.
Currently I only have one brand of magnum primers, but I’ll try that in the future.
Try RL19, IMR 7828, or RL 26 if you can even find it. Best of luck
Thanks, I wish I could
My old 270wsm loved IMR 4831 but with 150 gr partitions so big difference in bullets I'm sure of it. But that was a Browning abolt ii . I wonder if maybe rl22 wouldn't work or something around that. Like 19 or even 26.
If I could find those powders I would try.
@@hopefulballistics I know it sucks right now for powders. Rl23 was around and it's pretty close to 22. In my findings
Since the 6.8 Western shoots them factory at 2970 fps. I think it's definitely doable.
I thought the same thing, lol. I’m sure it’s doable.
Did You Ever Try To "Max Out" Your 30-06 With the 168 Grain Nosler ABLR's and Compare It to the 270 WSM Shooting Those 165 Grain Nosler ABLR's? That Would Be a Good Video! 👍😃
Yeah that would be
I enjoy learning from your experiments, but my takeaway so far is if you want to shoot the heavy 277 bullets: The 6.8 western is the easy button.
The 6.8 is a dead horse and is never going to get any more popular then it is right now. Winchester which also owns Browning is not pushing that cartridge and Hornaday Wouk’s love for it to disappear so the PRC’s advance even more and they are going to push all their efforts for that to happen😳 o I forgot that Winchester and Browning are not hardly any guns in 6.8 so do the math and change the cartridge when the barrel goes out😢
@@edwardabrams4972 time is a fickle entity. The 300 prc was all the rage when released. It hits the same targets at nearly the same distances as the Lapua for l half the ammo cost. Albeit less energy, then the 7 prc is announced and by the numbers stomps all over the 300 prc in terms of trajectory. Then the 7 prc’s chronograph results come back as disappointing as my pto request during Christmas. I agree the 6.8 will fall to the wayside with some very loyal followers and the prc’s will continue succeeding. But I still believe the 6.8 western to be one of the best short action cartridges of its type. I hope it sticks around. Though I’m waiting for the 25’s to make a comeback.
Simply put, it’s fun to test, and I don’t have a 6.8 Western currently.
Huh! I didn’t realize elevation made that kind of difference.
Oh yeah! I’ve played with 165 ABLR’s in 270 WSM and 270Win. Across the street is a small airport with an elevation of 83 ft. Shooting range is a good 20 ft lower, and I’ve yet to get a 165 ABLR to stabilize. Now it will in my 6.8 Western, but it has a 1:8 twist. I’ve also done it at different temps, and it didn’t matter.
Huge impact
@@hopefulballistics well? Would temp and humidity have an effect as well on bullet stabilization?
Interesting dynamics
@@user-cl7jw7td5q for stability, definitely. The colder and more humid the denser the air. The denser the air, equals less stability.
Use VV N565 or Reloder 22
Thanks
You must remember the 6.8 Western has a 1:8 twist where most 270 WSM has a 1:10 which makes a difference!
Makes a difference in what regard? I don’t think it would be a massive difference in velocity, minute difference sure. Remember the WSM has a greater case capacity too. It should be better than the 6.8, by at least a bit.
@@phild9813
The difference being the 6.8 has a faster twist and a longer throat to enable the bullet to be seated out farther than the 270 WSM. I was thinking of changing over to a 1:8 barrel with a longer throat and it would beat the 6.8 then but that’s the difference.
I’m not having any stabilization issues.
I understand what you’re saying but I’m not having case capacity issues either.
I would also be interested in the barnes 155 gr lrx bullet test! I have 2 270 wsm loads 1 using barnes 110 gr ttsx and 1 using 129gr lrx both about a grain to a grain off max in the barnes manual and both shoot 1 hole groups I'm not sure of the velocity but the accuracy is out standing ,will the heavier coppers be able to get the velocity a copper bullet needs ?
It’s on my radar. Thanks
Curious if your chronograph corrects velocity based on bullet weight and distance to the muzzle? Mine corrects 7-11 fps depending on bullet caliber and weight. Its not much but I use the Caldwell about 12 feet away from my bench (10 feet was too close, my fire breathing 26”barrel of my 6.8 Western was blowing my light shades off 💨). Example- using my 1-10 twist 270 Winchester 22” barrel with 170 grain Winchester power points- 3 shot measured average was 3026, but calculated average was 3036 fps. This was using re-used Winchester powder 54.0 grains. … and yes it was stable, I’m at 4600 ft elevation.
I don’t think my chronograph does that.
Stabilizing is about barrel twist not cartridge .
It is well known the 270 wsm is 1 in 10 twist.
Ramshot LRT. Re22, Staball HD, Retumbo. Curiously, I'm testing two Tikka 7mags and H1000 didn't produce near the velocity I anticipated with 140 Barnes TSX or 150 TTSX bullets in either rifle. Retumbo, Magnum, Re22, Staball HD are doing well. H1000 is an odd powder but generally speaking there's nothing I use it in appropriately where I can't get outstanding accuracy, SD and ES numbers. Thus, I use it a lot and kill a pile of 4 leggers with it in my loads. For 2 decades I was essentially a speedster. I'd ONLY consider the fastest I could get in whatever I was loading. Then realized that lobbing bullets like ballistic tips about as fast as a softball pitcher underhanding a ball killed game just fine way past 400 yards as long as it was an accurate load. But then when I try Barnes bullets I want that top speed.
The two 7mags are IDENTICAL except for the stock. Both blue actions, blue barrels, one is a "lite" and the other is a "hunter" so the latter has the walnut stock and the Lite had the black polymer stock. However, the two different barrels are a stark contrast on speed and I verified this with factory Barnes 139 LRX ammo with 2 different LOT numbers. In both cases, the Lite shoots about 100 fps faster. So what that means is you just may have a slow barrel on your 270WSM while someone else with the identical rifle may have an even slower barrel or faster.
My testing in the Lite Tikka T3x 7mag, 150 TTSX, new Nos brass, Fed215M primer:
Retumbo Reloder 22 Staball HD
70.0g - 3008.2 fps 66.0g - 3038.6 72.0g - 2947.2
71.0g - 3086.7 66.5g - 3059.3 73.0g - 3003.1 (stopped)
72.0g - 3111.1 67.0g - 3098.3
72.5g - 3102.4 67.5g - 3135.1 (no pressure)
73.0g - 3134.6
73.5g - 3149.3 (no pressure)
I stopped the Staball HD because the case was getting really full at 73.5 grains and up, and it was running behind on velocity. The Retumbo printed the last 3 charges into a 1/2" group.
7mag Hunter with 140 TSX, same brass and primer (note speed jumps compared to 150 TTSX)
Retumbo
70.0 - 2909.1
71.0 - 3053.8
72.0 - 3107.1
72.5 - 3161.4
73.0 - 3118.7 (flat primer)
Magnum
73.0- 2854.2
74.5 - 2947.2
76.0 - 3075.1
76.5 - 3092.2
77.0 - 3092.9 (the latter 2 in the same hole, no pressure)
Staball HD
73.0 - 2980.8
74.5 - 3046.5
75.5 - 3141.3 (no pressure, still going up on powder)
What is interesting is the Hunter rifle has a slower barrel. And a fired case is 0.002 longer at the shoulder than those fired in the Lite/synthetic rifle. but, in some cases, I'm reaching pressures sooner. Ultimately I think you should really try LRT in that 270 WSM
I appreciate the valuable information!
You’re having my luck but I’m trying to get my 28 nosler to group at least m.o.a tried retumbo h-1000 mag pro my gun will no shot a 195 grain bullet going to try smaller grain
Thanks for watching!
Imr 7828ssc, reloader 22, or n170 if you can find some, should get you 3000 fps
Thanks
but you still have a barrel twist rate that is to slow.. I think 6.8 was just a way to sell anew gun
The 270 wsm is a great cartridge but was never pushed by Winchester or Browning to manufacture more guns and ammo so it’s just slowly becoming a handloaded only cartridge. You would be better off buying a 270 win with a faster twist barrel and a longer throat🙌 just my two cents of 60+ years of hand loading and collecting rifles
Thanks
try the 155 lrx
I’ve thought about that
What bullet puller are you using for overpressure rounds you don't fire?
I use the Frankford Arsenal one, and the Lyman one for WSM cartridges.
Need slower burn rate period. Retumbo, 8133, n570, R33 will get you there
Thanks
Reloder 26 or Maybe LRT
Thanks
24" barrel?
Yes
You need a longer barrel. LOL
I guess so, lol
Instead of heavy at decent velocity why not push a Barnes 110 TTSX at Mach Jesus! 😇
I’ve also shot 85 grain and hit 3600 fps without trying.
Your never gonna reach 3000 with that short barrel
