Can anyone tell me if Shilen pre-fit Savage large shank barrels come with a shoulder on them? The McGowen I've got for it does not but the Shilen I just got (new) has one. The barrel nut will go over it slightly until the threads contact the shoulder. Additionally, my action will only thread on for 2-3 turns before it stops. I've got a good barrel vise but no action wrench but I never needed an action wrench to screw on the McGowen barrel.

Anybody have any ideas as to what my problem might be?

Thanks!
