The first thing most change is the barrels. I like Lone Wolf personally but they handle loads better and if you plan to use uncoated lead then the rifling on stock barrels jam up.

I've used CCI and some Winchester large pistol primers both worked fine for the rounds but CCI feeds better in my presses. As for powders I use 800X and Blue Dot regularly. Just stay away from max loads with 800X unless your powder measure is accurate. I use 135gr Noslers for nuclear loads that scare the hell out of others at the range, 180gr for most loads, and 200 gr hardcast beartooth bullets for hiking in the woods.
