The primer crimp on 223 is one of the most common types of ammunition. Primer crimping only occurs when a rifle shell is seated too low in the casing. This makes it more difficult to extract the cartridge and increases your chances of an accumulation of carbon at the base that can cause a jam and affect bullet velocity.
In this article, we’ll explain what causes primer crimping on 223 ammo, how you can avoid it in general, and how you can fix it if you’re stuck with a jammed round.
Advance Tips: How To Remove Primer Crimp On 223?

This article gives you step-by-step instructions that will take the guesswork out of a primer crimp removal. The first thing you need to do is to remove all primers from the casing, then dump all remaining rounds (without primers) on a hard, level surface. Inspect your rounds for deformities or inconsistencies in the brass and discard any rounds with such defects. Then, open your reloading die adjustment screw 1/4 turn counterclockwise, and set it so that it exerts enough pressure on top of the engaged shell holder but not too much force as to deform brass or distort cases.
Next, place the hand priming tool into the press and close the ram all the way down. Place a case in between each of the jaws on the holder. Place your thumb over the priming arm and turn it until it stops but don’t prime the brass! Remove your thumb and gently slide it to make sure that you aren’t bending primers in any way. Close your shell holder and come back to your press; turn its adjustment screw clockwise 1/2 turn, depress all three of its locking mechanisms (if present), then lower your ram completely down.
