Seems like the commercial FN action I used which was originally chambered to the .270 Win. took some way too heavy reloads from the guy I bought it from. PJ
So the problem was finally diagnosed. Lug set-back?
That's what I looks like. The sad part is I remember that rifle doing just that with factory .270 ammo. Then I just stuck the rifle way back in the safe and forgot about it until I had the custom made. Guess I'll just have to scavenge a receiver off on of my good FN rifles.
