    Again without beating a dead horse, I own a win 43 in mashburn bee. Alot of shooters talk about "glass bedding" the barrel and I was just wondering what the heck is that and also why would that improve the accuracy of a rifle. I understand the principle of "free floating" but the glass bedding thing is over me. I'm always looking for that extra 1/4". If there are any suggestions, I'm all ears. Oh and by the way, my son got his first buck this year. I was very proud if not more than he was(6point!). He just turned 13. This is his 2nd deer!

    It's all about the oscillations of the barrel as the bulle is moving from case to muzzle. the full glass bedding tends to dampen or reduce the amplitude of the oscillation wave, which means the barrel's movement is less- since the movement is less, the bullets have a larger period of time for exiting the muzzle while it is pointed in the same direction. The weak link in glass bedding is that the forend of the stock is wood, and wood is subject to warping. and if it warps, it takes the fiberglass with it, so now the situation is worse than before, because the glass is pushing in one direction or another on the barrel, which causes accuracy to go totally out the window. So you'll see folks that believe full glass is great, and they are right, and you'll meet others that despise it, and they are right too. It all depends on the other parts of the rifle and how compatible they are with each other.

    Full glass bedding is used mostly for barrels that were not straight to begin with (most factory barrels are horribly bent). The full bedding, when done correctly puts about 15lbs of upward pressure on the entire barrel and around it's sides in the barrel channel. That dampens the "non-concentric" oscillation of the barrel,the inconsistency makes for a very non-uniform frequency from shot to shot, and therefore dis-similar POI. A barrel which was closer to being straight from the factory will prefer to be free floated as the frequency will remain more consistent from shot to shot, and addind pressure to that barrel degrades it's accuracy potential. Try placing a folded business card under the forearm/barrel so that it is TIGHT. Then shoot a group,..if that group is better than before, then you need a pressure point,..if it is worse, you will benefit from free floating.

    Also,..sometimes a patch of bedding just ahead of the action and under the first 1-2" of the barrel will bring one around quite nicely,..but this is usually with THICK target barrels.

    why chase the game when the bullet can get em from here?....
