I've always enjoyed tinkering around with different reloading components for both centerfire and shotgun. Never taken it to the level this guy does but it's still fun to find loads that perform well.

I've been playing with different bullets for accuracy.

I'm here to tell ya, at distances of 500yds plus, hunting bullets don't cut the mustard.

I tinker with a load till I find one shoots good, under an inch at a hundred, then just load it and quit fooling around. One of the things that I found is how different brands of primer can change things. Just that one change can go from lucky to give 2 inch groups to just under an inch. Some tinkering does help, but once it's fixed quit messing with it
