...I kept coming back to IMR-4831 with my Swedish Mausers that came and went over the years, and now the Ruger 1A seems to dote on it. Frankly, I can't try every suitable powder known to mankind and IMR-4831 returns consistent performance so I stopped there..
Tell me about it...
Am considering switching to a modern powder at the next bulk buy, but IMR 4831 has been so good for the .270 WIN over the years, and now also the 6.5x55mm, that it's hard to walk away from.
