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.
chambering a round over and over?

Re: chambering a round over and over?
I have never in my 50 plus years of hunting felt the need to chamber around before I got ready to shoot.
How every, I've shot a lot of High Power and 1000 yard matches with M14/M1as and ARs where I chambered a round, caught a change in conditions and pulled the round out setting it back a few rounds. I never saw any change in the slightly dented primers but I had more then one dent.

Re: chambering a round over and over?
Slam fires are possible.
They are rare and I have only seen it once with a very, very dirty gun. There was resistance between the pin and bolt with contributed/caused the issue
The military uses a harder primer cup to help avoud this problem.
Being a coyote hunter I have gone some time loading and unloading the same round. (.223)
Do a internet search "slam fire"

Re: chambering a round over and over?
I would just rotate the rounds in the mag. We never had any problems overseas when constantly loading and unloading.

It is possible for primers to be deadened by repeated chamberings. There was talk on 10-8forums about multiple le agencies having Hornady 5.56 TAP fail to fire after being rechambered several times in ar/m16 style rifles. That is the ammunition I use in my m4 so I conducted some testing where I would rechamber a round multiple times and fire it. I worked my way up to 30 rechamberings and never had a round fail to fire. Even though a primer problem is highly unlikely I try to limit rechambering the same round under any circumstances where I can't afford a misfire.

Re: chambering a round over and over?
cycle your rounds as mentioned and you should be fine. Not chambering a round in a semi auto when hunting until you are ready to shoot? I guess you would do the same for bird hunting with a shotgun...rack a round when the birds flew? I'm all about safety but I think thats pushing it a little too far. I hope im just misinterpreting what you said there.

Re: chambering a round over and over?
I have done quite a bit of different kinds of hunting and have not seen anyone, anywhere, leave the chamber empty until they see a target and are ready to shoot.
I would be more concerned with bullet setback than primers.

In my home defense AR I've probably chambered the first round 20 times or so just from unloading to clean and whatnot. The bullet had all kinds of scratches on it and a noticeable primer dent, went target shooting a few days ago and it fired okay.
