Short stroking? was created by ADTREM
Failure to feed Chamber is empty with rounds in mag. bolt does not lock open and trigger clicks. Hornady 150gr T.A.P.

Ammo is hard to come by so I grabbed a couple boxes to try. I'm wondering if because these are touted as law enforcement ammo they are a weaker load as not to over penetrate? Started off with other ammo and function was fine. Didn't have a chance to switch back. Any thoughts?

What brand/type of rifle do you own? How many rounds did you fire prior to using the Hornady ammo?

Went thru 20 or so rounds of soft point. I know it's not the favorite of this rifle but I had some left an wanted to give it a try. No prob with that ammo. Checked chamber for fouling and it was clear. Oh, it's an armalite ar10 I forget the exact model but 20" barrel standard stock. (not m4 stock)

If other types of ammo worked - and continue to work - well in your rifle, I'd wager it was the ammo vice the rifle. If the problem occured with all types of ammo, then I'd start looking for a problem with the gas system.

Also, check your feed ramps for lead build up since you were firing soft points.

It will fail with any ammo. Ran ok for a while, then started acting up again. thanks for the tips on where to start looking. I will get into it this weekend.

Also check the gas block, gas tube and carrier key for leaks.
