I thought some of you might be interested in this: https://imrpowder.com/wp-content/upl...-loads-r_p.pdf
Trail Boss is for light cowboy loads, but apparently you can load it in anything. I decided to test it out in my .358 Win Encore pistol. Because .358 is .308 necked up, the formula led me to the same starting load of 10gr. Recoil was, well there wasn't any. At 50 yards I put five rounds in a ragged hole, but POI was about a foot higher than POA.
I'll probably play around with it a bit more because I can only stand so much fun in one day with rifle caliber pistols.
