first round he fired stuck in the barrel...ok,seen that happen before,squib round,no big deal,knock it out with a down,check the barrel and go on....he did that,fired a second round,same thing...so he contacts me and is a little pissed his new gun doesent work....and I feel bad cause he Thinks I sold him a dud.
If bolt is in battery, the primer is being sucessfully ignited by the firing pin and he's able to hammer the bullet through the barrel and out the muzzle (IE no barrel deformation) how can the gun be to blame? Unless there is pressure escaping through a fissure/hole/deformation in the barrel or escaping back through the bolt and into the shooter's face because the bolt isn't in battery? I submit that a functional 223 round with roughly 50k PSI should be able to propel the projectile through the barrel much better than he can with a hammer.
My first reaction was bad ammo,incomplete ignition of the powder,etc.
Unless there is something seriously wrong with the chamber or barrel that is allowing pressure to escape somewhere this is most likely situation. See below.
Other then ammo,what else would cause this?excessive carbon build up in the gas tube maybe?im honestly at a loss here and want to help him get it running.
I once bought an M1 Carbine at a gunshow. When I took it out to shoot it, I had exactly the same problem this gentleman is having. After hammering 4-5 bullets out of the barrel from different manufacturers I got suspicious and tore the rifle apart. Turns out there was a hole drilled laterally from left to right inside the chamber. Some idiot had attempted to deactivate it by drilling holes through the chamber and I assume the intent was to stick a rod through the holes to prevent rounds from being chambered. The rod may or may not have been placed since I got the gun (so did the dealer) in that condition without the rod but the damage had been done. The gas pressure was escaping through the sides of the chamber via those 2 holes and there wasn't enough leftover to propel the bullet out of the barrel and cycle the action.
From what I gather from your post, nobody performed a shady deactivation job on your rifle and it was working before so it has to be the ammo.
