hey everyone. had a round that i loaded into my ar 15 from my mag by releasing the bolt and when i ejected it the primer had a nice size ding on it. more than a nick from the firing pin. I recently cleaned it and pulled apart the bolt and parts and put it all back together and it functions fine. but maybe i missed something. should my firing pin be leaving marks on my primer at all. this really suprised me since i have never seen this before...] any suggestions as to what may be wrong or what i should do. i am afraid to even load one until i am at the range or in the woods and gun is pointed in safe direction. not that it wasnt when i did it but you never know. ... please help if you have any input thanks.
