The "trouble" I had was I did not try enough powder bullet combos at first. I never shoot factory ammo and used what I thought would work when looking through my manual, worked up loads and really wanted to shoot barnes bullets ( I dropped that bullet and load combo idea). Until I read here of a load combo I had not tried yet. Double checked it in a manual and loaded up 3 shots to try, WOW Now all 3 of ours are sub m.o.a. shooters. So my guns problem was my ignorance in the beginning. Good luck, mine is my favorite handi and has put the most meat on the table. thejanitor
