Thanks to 7.62X39, I've got my trunions installed and was ready to install the barrel today. Used some RCBS case lube, a brass 5/16" bolt and a big hammer. It started slow but went without too much force. My question is, just how tight should the "press fit" be? This didn't seem very tight at all. Will the pin hold the barrel in place? The pin took alot of force to set. This is a matching trunnion and barrel.
