New grendel, wont fire

[Deezil]

a few more pics, and screwing around I took the round that was beat to death and pulled it, shoved just the case in and bolt wont close enough. Knew that, so, took a wood handled hammer and lightly tapped the back of the bolt to see how much it would take to get it seated, a couple good taps and it popped in place... Tried a clean case with no marks on it and did the same thing, still no marks on it, heck if I can tell where its binding, but it did go all the way in, its really tight alright, getting them out takes a few taps on the T handle. Wonder if I forced a few in there and fired them if it would 'wear in'?
