When you fire your rifle, an upward motion of the barrel is created which causes a pulling action on the stock. Dependent on the caliber, this can be quite violent. If your action isn’t bedded firmly into the stock, this movement can create the opportunity for your barrel and stock to collide, changing the point of impact on your shot. Boyds stocks are meticulously engineered and machined from the most stable materials to maintain a free floated barrel to reduce the opportunity for collision between the barrel and stock. However, in some cases it’s recommended to bed your action. First would be in heavy magnums or firearms with excessive recoil. Even though we install reinforcing cross bolts in all our stocks, bedding your action on these firearms is added safety, and highly recommended. Another case is this firearm, out of the box, this stock and firearm consistently shot under a 1” group at 100 yds., however, I want to improve on this, so to do so, glass bedding the stock will all but eliminate the movement you’re seeing when the action isn’t bolted into the stock.
