.45acp with small pistol primers

[RandallZ]

I've been trashing them, and when given boxes of Win BEB small primer stuff at the LASD range, I just leave the brass behind. Now that I'm putting my reloading bench back to work, leaving brass behind bothers me. Also, I'm pretty sure that I can get thousands of rounds of small primer brass just for the asking.

I'm wondering if powder and primer improvements have made large primers pretty much obsolete.
