An interesting problem arose with my favorite barrel, a .35 Rem hunter. I free floated it using thin washers. While cleaning it, the treaded socket slipped out of the dovetail slot. I'm think that this may become a problem with other barrels I've floated. Normally, as you tighten the fore end screws, they draw the fore end down against the barrel and pull the dovetailed socket tighter in the bevel. However, when you free float using washers, the first contact is the washer against the shoulder of the screw socket. The screw and the socket essentially become one piece at that point and no pressure is exerted against the matching dovetail bevels. Heat, recoil, handpressure, etc. can work the dovetail loose.
Has anyone else experience a similar problem? I'm thinking I'll go back and redo all my barrels using Graybeard's tape pad method. That allows limited contact between barrel and fore end and allows some pressure to be put on the dovetail.
I'm I wrong here?
