Home Forums Reloading Big Game Rifles 270 Win, Re 26, 150 NPT - who needs a 7 mag?

Shot more Re 26 this AM in my Kimber 270. This stuff is for real:



My rifle likes 61.0 grains in a WW case seated 0.020" off. Primer doesn't seem to make much difference but seating depth does. From top left: Fed 210, WLR, WLRM. The target in the lower right is Fed 210 primer but seated 0.040 off. It didn't like that...........

For reference the orange square is exactly 1". Avg vels were 3046, 3050, 3031 for the 0.020 loads.

I compared this load with my favorite 7 RM load (H1000, 160 NPT, 3050). The 270 gives up next to nothing.

This rifle/load combo is likely going to WY and CO this year in search of elk.

Nice! That'll penetrate like a fine stud horse. Possibly over penetrate... Use with caution

That's some serious velocity. I'm 100 fps slower using 140gr bullets and H4831sc with my 270. Great groups you have too. Are you getting any pressure signs with that recipe?

No pressure signs. Alliant data indicates 3022 with 60.8 grains and 150 NPT. Mule Deer will likely chime in with his load data. I think he ran it to 62 grains.

The other thing I noticed about Re 26 in my gun is the group location with different primers. I didn't post the other targets but 60.0 grains shot 2970ish and were in the same location on the target as the 61.0 loads. In my gun it seems to be pretty insensitive to primer and charge. 60 gr shot about 1.3". Vells and groups from this round were similar to the first batch of loads I tried a few weeks back. I'll shoot a 5 shot group son to see what the group does. I suspect it will stay under 1.25" gross.

I may try some of that powder if I run out of H4831. I use Alliant's RL17 in my 338-06AI with great success. Cheers.

Nice to see some confirmation here.

I started at 60.8 grains of RL26 for 3,010 mv out of a 22" barrel.

I then lengthened the COAL bumped up the powder to get better accuracy and a little more speed.

I'm liking your velocity with that 150. Guess I need a jug of RL26. As with a lot of folks,I'm on the H4831 train. Some 7828 under the 150 grain. RL26 might be the next big ticket.

I'd opine that if your rifle shoots H4831 under 150s, it will shoot Re26. My second best load is H1000 and/or H 4831. It likes both equally well. The bonus is, you'll pick up 100 ft/sec.

I've been watching this powder for a while. I have a 25-06 Sendero SFII. That 26 inch barrel ought to be giving me 3450ish velocities using Barnes 100s with decent accuracy, Instead, no matter what I try, it likes to throw 2 and one when it gets above about 3230. It doesn't seem Picky at all at about 3230, other than seating depth. Hit seating depth and 3230 and it'll shoot sub inch.

I think 26 might be my last attempt before I surrender. Alliant data shows ~3350 with 24 inch barrels and other 100 grainers. The Barnes tend to go a little faster so I hope to manage Alliant numbers anyway + a little something for those extra 2 inches of barrel. 17 and 22 gave me better numbers without pressure at 70 degree temps. 4451 is on the short list to try in this rifle too, but I have less hope for much extra speed out of it.

Very impressive! I have been using H4831 in mine with the 150 NPT and "only" getting 2830fps. Might have to try some RL26.

Ill try it for 100 fps.

I've been using RL26 for about a year now. Took a couple of months to get up my way after it was released and became available, but I'm getting 3150 fps in my 7 WSM with 162gr A-Max bullets with great accuracy.

Very cool B. I'm going to be trying this as well.

I wondered how it would work in the 7Mags, and now I know. Your data jives perfectly with Alliant's data for the 7WSM and 162AM, which shows 3150+fps. Gotta find some '26 to try!

OK, so can anyone explain to me why RL26 in the .270 Win can hit 3050 with 150gr bullets;

7mm WSM can hit 3150 with FOUR different 160gr bullets;

But the 270 WSM barely breaks 3100 with 150gr bullets in 1 out of 3 different loadings?

Possibly because you're getting to the point where a slower powder would work even better with 150's in the .270 WSM, is my guess. I wonder if RL33 would give better velocity.

That's some fantastic velocity with that bullet. I've been shooting the 150 NPT in mine for years at about 2850. Deer don't go to far after being hit with them and it will shoot 5 touching at 100yd and super reliable.

Sounds like a really great combo.

Good luck and shoot straight

Pressure.

It's all guessing unless you have equipment to measure it.

I think that the chamber geometry of the 270WSM may have something to do with the lower velocities (no throat). When I got mine years ago I was blowing primers trying to exceed 270Win velocities 150 grain bullet. I even had it throated and still only got a little over 270Win velocities. Hodgdon only lists 3070fps with Retumbo so slower powder doesn't seem to be the answer. Haven't played with the WSM in a while though. Western does show 3100fps with Magnum but never tried that.

My 270Win gets 2950 with Magnum and shoots the 150 NPT just under 1", so see no need for WSM.

All that extra gayness adds more drag.
