I bedded two post-64 Model 70's about 50 years ago using AccraGlas (this was before the Gel). As I recall the box had a little envelope of shredded fiberglass in it. Followed the directions (it was my first time) and the only problem I had was the fit of the recoil lug--it was extremely tight to get out (had to use a rubber mallet on the bottom of the barrel) and would not go in again until I relieved the front of the lug recess with woodworking chisels. The next rifle I put one thickness of electrical tape across the front and sides of the lug and painted it all up with release agent and this solved the problem. Came out relatively easily and went in with only mild pressure. I also pressure bedded the barrels with a teaspoon of the mix just in front of the fore end screw. Both rifles, a 7Mag and a .25-06, were consistent tack drivers from that point on. I dont hunt when its much below 0 (Colorado) and Ive never had a failure of bedding. Started buying pre-64 Featherweights after that, and never had a need to glass bed any of them. All tackdrivers with factory wood and inletting. Thanks for your post though. Very informative.
