Hello all, So I'm new to reloading 223 but have been reloading for larger calibers for a while now. These primers are so tough to seat. I feel like probably 3 or 4 out of 10 seatings damage the primers because it's to tight and I actually just had one go off while seating which made me have to almost change my pants. Doing research it seems as if the primer pockets have been crimped. What stuff are you guys using to get rid of those? Hoping for a drill option so I can chug through brass prep quickly. Thanks for your time and hope to hear from you soon!
