just got a new to me 500 SW barrel. It fits perfect on one of my SB2 frames with a .002" shim cut from Brownells shim stock. I test fit it and have been opening and closing the action and the shim does not seem to move around. Is it safe to use the rifle without epoxying the shim to the barrel lug? In case it is important, I will not be using factory 500 ammo, only light reloads comparable to Trapdoor 45-70 loads, maybe a little hotter.
Thanks
