when he chambers a round multiple times throughout a moth or so w/o firing slowly the brass becomes more and more dented? also when he chambers a round it creats a mark almost as if the firing pin was striking it with a lil force, i looked at alot of other ppls it dosent happen not nearly as bad as his?
ne thoughts? headspace?

Don't do that. If a round has been chambered a couple of times, it should be thrown away. The bullet is likely to get set back, causing pressure problems, and other problems.

Like I said, don't do that.

I find it much easier once the round is chambered, to just shoot it the first time!

check function/test/play with a dummy round/snap cap not live ammo.

Re: times friends M16 A4

The firing pin thing is normal in AR's...it is free floating, not captivated or under any spring tension..when the carrier slams closed inertia causes it to drive forward and tap the primer..this is why military ammo has a hard cupped primer, reduces the chance of a slam-fire. If a round is chambered and then extracted as a result of not firing, it is the accepted practice to rotate that round further into the magazine and to not load it on top again, as mentioned repeating chamberings will do funky things to the cartridge.
