Re: 270 WSM (IMR 4350, R19, R22 results)
The only 130's Ive ever shot were factory federal ammo given to me. I shot them to get the brass. They were kinda cool tho. Very little recoil.
The two best powders Ive used to date on my 270wsm was RL-19, and IMR 4831, launching 140 grainers, and 150's. The IMR 4831 was ok for velocity, but grouped very well. But the hands down winner for combined Velocity, and group size was RL-19.
RL-17, with the 130's and you may have some success like Bigngreen stated.
Any particular reason your shooting 130's vs 140's or bigger. Not nockin your choice, just curious.
