Hey all,
I live up in Canada so temps go from -25 to 90 F. looking for a powder that is not sensitive to temp changes for my 270 Win. I've tried RL22 with good results when it was warm (consistently less than MOA), but now when it got to freezing, the groups seem to open up. :banghead: Read from others that their MV changed 130 fps from summer to winter (Idaho) so that could explain some of it.
Looking at these powders (and other suggestions) to try next. Bullet is 130 SST and gun is Browning A-bolt with 22 in barrel.
H4831sc
H4350 (some say this is more of a barrel burner?)
Ramshot Hunter
RL17 (less temp sensitive than RL22?)
Others???
Anyone had experience with these in temp changes?
Thanks.
