Won't chamber....
Using SSK dies (Hornady make), .221 Fireball brass, 220gr SMK BTHP, 12.4g of H110, 1.360 case length, 2.216 OAL. The upper is a recent M1S upper, 300 Whisper. Factory SSK ammo chambers just fine.
Tell me, what am I doing wrong, how do I fix it?
Oops, wrong sub-forum. Would a moderator please move this to the proper sub-forum?
