Best Powders for 12" 300-221

[A62Rambler]

Well, a call to the ATF and I've got time to wait. They guessed it would be 6 weeks before it even gets to someone to start the approval process. The guy told me it would be May before I got it back with a stamp. It's going to be a long wait. On the bright side, I should have had plenty of time to gather everything I need. I guess I'll try AA9 and maybe N110 from Vhitavouri. By the time I get it you guys will have loads worked out and can tell me how well H110, 2400, 296 and Lil Gun work.
