I know this is a very old thread. I am had fantastic results with Federal Power Shot. Both accuracy and terminal results. I was jus considering the the Lee classic loader to leave at our camp with some primers projectiles and powder. I decided I'd just buy some loaded Federal power shok instead.
Loading a few rounds at a time as you need them at your hunting camp seems like a suboptimal option to me.
I think that you'd be better off to buy 5 boxes of factory ammo from the same production lot and shoot it up. When you're done with that set of 100 rounds, buy another set of 100 rounds and repeat the process. I recommend this to my casual hunting acquaintances, but they often don't want to spend the $$ necessary to buy 5 boxes of ammo at one time.
