Yes, you'll have fun with 300 BLK. It's the most recent caliber I've added to my reloading bench.
Any more I try to limit reloading to only calibers I shoot regularly. Problem is, I DO shoot these regularly. Because I reload I can shoot economically, have ammo on hand when it's scarce, and I can cast my own boolits for most of them.
I s'pose if I could find a way to reload 22 rimfire I'd prob'ly try that too.
Reloading is an evil addictive disease...but it's fun...

DAMN! Do you sleep?
I'll be off visiting other threads. My little tiny list and I will be leaving now! You have yourself a good evening!
