Mike, As long as the bolt is engaging fully, the fit on the shotgun barrel really sounds better to me than the ML. You want things to be pretty snug. I have found much less difference in Encore barrels than Contender barrels. Of course the span of time for manufacture of the Contender barrels is 6-7 times what the Encore is. I have 6 Encore barrels including a Muzzle loader, and I see very little difference in the lock-up on them.
GOOD SHOOTIN', Walt :grin:
