Today I've been shooting some cci subs, and nearly every shot is a fail to fire. I cock the rife and pull the trigger again and it works great.
This is a new pack of ammo and was cycling / firing the same ammo (different pack) yesterday.

Hopefully if you look closely you'll see two firing pin marks, one very much lighter than the last.
What's causing this? Is it just the ammo and the inaccuracies in it's manufacture or do i need to swap out the firing pin?
