I sized and trimmed 1000 pieces of 45 ACP brass...
I would hate that too!
Case prep is, easily, my least favorite reloading chore. I'd rather throw all my pistol brass away and replace it with new stuff, if I hard to size and trim it all.
I'm slowly working my way through a couple thousand .223 cases. Even with an RCBS power trimmer, it's not much fun. A few hundred here and there, is about all I can muster for patience.
