I have been using my dpms LR-260 for hunting lately and as i chamber a round it leaves a small indent on the primer as with any of the other ar's i have used or any ammo. I was wondering if i am using this for hunting and every time i go out and do not shoot and have to eject the loaded round, how many times is it ok to chamber that round again? Never? A few? depends on the indent? or should i just start slowly releasing the bolt and using the forward assist? Thanks for your help.
