Home Forums Reloading Big Game Rifles Best Powder For The 270 WSM ???

My son likes Magpro with 130 gr Ballistic Tips, I like Reloder 17 with 130 gr Accubonds, and Accurate Data 86 Extruded with 150 gr Ballstic Tips. Need to try some Magpro with some 140 gr Noslers, it might be the best combo of accuracy and velocity.

I use R25 and 140's and get 3175fps with excellent accuracy. I believe I'm 1/2 grain under max.

My winchester model 70 is very fond of 130 grain pills and R19

Another vote for I4350 and MagPro

I've used both RL22 and Magpro with good results.

A big case with a small hole in the barrel always say's a slow powder to me. I tried some RL-22 in my 25-06 and my 6.5-06 and the stuff worked great. I also have some good loads with IMR4350 and H4350. Never had good loads with 4831'a except in magnum cases, you might want to try one of those.

My 270wsm prefers 140gn Accubonds and 67.5gns of W780 Supreme for 3150fps.

67 gr of RL19. 130 gr Interbond.

24" Model 70, Winchester brass, Winchester mag primers, 130 gr ballistic tips, a max load of H4831 gives me velocity and accuracy.

RL22

I use 62.8 gr. RL17. 3400 fps in 80 degree weather With my Savage 24 inch barrel and 1/4 inch groups.

Wow,you must have a fast barrel, best I can get is 3280 with 63 gr RL 17 using the old Barnes xlc coated bullet.

Standard 1 in 10 twist. You can't achieve the same velocity with molly coated bullets. They are slower per given charge.

I know you said 130's but I use 150's in all of my .27 cal. rifles. FWIW, I've pretty well settled on Retumbo with IMR-7828 a close second. I'd guess H-1000 would be good too. I tried Rldr-25 and velocities were quite anemic.
Just something extra for you to think about.

I've been running R19, But I may have to find myself a can of MagPro.

I am with Bear in Fairbanks. My .270WSM loves Retumbo and Nosler 150's BT's and Partitions.

For 140 grain bullets H4831 has done best so far.

For 130's Imr 4350 has worked.

All my loads will shoot sub MOA with the 150's shooting 1/2".

I have also been fortunate to have all my chosen loads shoot within a couple inches vertical of each other. For an average hunt I could just grab a box of ammo and go.

Resurrecting an old thread for the sake of some new powders having come out since this was first asked.

Seems Mag Pro got the vote.

Does this still stand.?

I have had good luck with. ^^^^^^

Not surprising, I used to run it in a 270 Wby I once ran.

Magpro and 150 partition and fed 215 primers.
