I am hoping to get some feedback from you all about a possible dent/deformation on the hump back of my "new to me" '65 Auto-5. I hope the pics are clear enough, but just inside the humps perimeter... there seams, to me anyways; that the hump is dented outwards a little. I'm wondering what could cause this? The bolt slamming back into the reciever? Should I be worried or am I clear to shoot
I can barely make out what looks to be the rear face of the receiver being pushed outwards. That is due to too heavy of loads, way too heavy as a matter of fact, being run through the gun with the recoil spring system set for light loads. An occasional heavy load isn't a really big deal, but as this particular receiver shows-----a steady diet of them will ultimately cause exactly what you have going on there. I have seen three guns over the years that were constantly fired without a BFR (bronze friction ring) at all, just the recoil spring. That rear face was much worse than yours. If things have been shuffling around hard enough to "dent" the receiver, I can only imagine the innards have an equal amount of drama going on. I would yank the whole thing apart and do a close inspection!!
