The 270 will swallow everything from 4064 to RL25 IME with the medium-slow to slow showing best with bullets 130 gr and up.

I've only used R17 in the 270 with the 110 Barnes where it did well. I'd expect the powder to do good in the 30/06, the 338 Win Mag, and likely the 375 H&H as well.

Personally I defaulted to H4350 in the 30/06 with no reason to change so far.


Bob, what powder would you use for a 150gr. partition load in the old 270 win? I'm like you and love H4350 in the 30-06. It's so damn resistant to temp swings that it isn't even funny. I'd like to get the same results from my 270 with 150gr. partitions. I shot that rifle yesterday and the velocity fluctuates quite a bit when the temp goes up or down.


I finished up load development for my latest 270 shooting 150 gr Partitions. It got down to H4831 and H1000. 61.0 of H1000 was better than H4831 when I started shooting 5 shot groups. I use a drop tube and WW brass to get 61.0 in the case. Vel from my 24" Kimber is ~ 2925 ft/sec. IMR 7977 did fairly well as well.

I could use H4895, H4350, H4831, H1000 for the rest of my life and be really happy.

Adversity doesn't build character, it reveals it.
