I have a TBA M40a3 that I shoot a lot and I love to shoot it. The issue that I am having is that I use Lake City brass in it. When I chamber a round it goes it tight. I have a life time supply of this stuff and want to continue using it.
When I do chamber a round that is Remington brass it doesnt chamber hard at all. Now I do know that the LC brass is thicker than commercial brass. Would this be the cause of the LC brass chambering hard? Would it be better to have the chamber recut for 7.62 since I am using LC brass? When I was in the sniper platoon I dont remember any rounds that we were using ever chamber this hard. I have about 1k rounds down the tube right now.
Any help or thoughts is appreciated. I am also getting ready to build my M40a1 and want to know if I should have it cut in 7.62.
Thanks
