Looking for 270WSM powder recommendations

[Cookie114]

Im about to start loading for a new 270 WSM (24in tube) that I got up till now this is the first .277 caliber ive ever loaded for.

I have a handful of different bullets that a buddy has given me to try out which includes 129lrx, 140 sierra sbt , 140 interlocks and 150 LR AB.

POWDERS I HAVE AVAILABLE-
R-26
R-23
H/I 4350
H4831SC
7828SSC

So if any 270wsm guys see this and would like to chim in on your experience with these powder combos Id appreciate it.

H4831SC
R23

In that order. I like the Extreme powders from Hodgdon. I've shot untold pounds of H4350 & H4831SC.

With 140 Gr Sierras mine loves H4350, never tried anything else.

Do you know what kinda speeds your getting with your combo?

Right at 2980, 59.9 GR 4350, it will go up over 3000 but this load is 1 ragged hole.

Sierras are underated in their terminal performance IMO.

I'd try R26 first, my favorite is Retumbo for 140gr and heavier.

RL23 is what my rifle likes. 3380fps with a 126gr.

Is 71 grains compressed with RL26? Are you running a LA?

It's not compressed. The bullets are seated as long as the magazine allows. It is a standard short magnum sako action as they come from the factory. No modifications have been made to the rifle. Alliant book marks 70.3 as their load for the 130 TSX (they don't state max and min, just 1 charge per bullet) so I worked up from there.
