Re: Pillar bedded Vs Glass bedded

Elk County PA? I grew up there.

For the best accuracy, everthing has to be repeatable. One very important place for this is in the barreled action to stock fit. There are a couple ways to help keep everything consistant. The most popular are glass bedding and pillar bedding.

Glass bedding involves using epoxy to form a perfect mold of the receiver inside the bedding area of the stock. There are kits available that provide epoxy in black or brown and release agent. What's involved is basically coating the metal parts with release agent and mixing up the epoxy. Apply a coating of epoxy to the inletting areas and putting the barreled action back in the stock. When the epoxy cures, it will have a perfect form of the action. This will keep the action from sliding around during recoil. It also helps greatly reduce the point of impact shift when removing and replacing the barreled action from the stock.

Pillar bedding goes a step farther. When the action screws are tightened down there will be some compression of the stock material. This will happen if it is a wood, laminated wood, or synthetic stock. On all stocks, this creates stress. Stress is not good for accuracy. Wood will have the most stress. This level of stress will change with the varying humidity levels. To alleviate this stress, metal pillars are inserted into the stock to give a metal to metal to metal fit. This means the action touches the pillar which touches the floorplate. When a proper pillar bedding job is done and when the action screws are tightened down, there is no stress. proper pillar bedding jobs also include a glass bedding job.

All rifles will benefit from a proper bedding job. Even the rifles that have stocks with full length aluminum bedding blocks. They respond well to a skim coat of bedding material for best results. Rifles with fat, heavy barreles benefit most from pillar bedding. It cuts down on the action flexing during firing. I pillar bed almost all of my rifles. The ones that are not pillar bedded do have glass bedding. The guns that come from the factory with "pillar bedding" usually require bedding work for best performance. Usually just a glass bedding job will make them much better.
