Mine was too tight if i used an Elite bolt. Crush (.007+) was too tight with a Win209. Using a Mountaineer bare primer bolt its not bad with the Lehigh plug. A tiny bit sticky with a few primers until i polished the primer pocket for a minute. I do that to all plugs though. I dont think its going to need a shim atm. Maybe a .003 at most if it does. Primers fired without powder come out clean. Even the Feds came out pretty clean but im betting they will stick a little with powder. Not stick in the plug but stick in the bolt if head space is a little off. I ran into that with the Super DISC 45. Not all the time but often enough it was very annoying.

My Bestill plug with a .006 crush on a Win209 seems to work ok with a Fed209A also. I asked him to make it just a little tight for a Win209. Then i can use both as long as i sort out the overly long Wins.
