I see where it could be fun but I just want to crank out some rounds and go run the hell out of my cz!!! the bad thing is im kinda hard on myself for accuracy and if I cant rapid fire into a playing card at 21 feet (old bad decks of cards and post-it notes make good cheap targets) then its no good and the way my loads are working right now I would have to change my aiming and I don't want to do that.Experiment with velocity, do you have a chronograph? Then bullet weight.
I waited about 30 years to get a chronograph, that was 30 years too long.
The whole experimentation phase is the cool part of reloading, it calls to me.
