Most all my varmint and big game rifles have ben given a tune up. The actions with about one inch of the barrel has ben glass bedded, The rest of the barrel is free floated. The trigger pull is adjusted to three pounds. The bolt locking lugs were lapped on two of the rifles and the muzzle was lapped on one rifle. I work up reloaded ammo untill I get one inch or less 100 Yd five shot groups from the big game rifles and .75 inch or less size 100 Yd groups from the varmint rifles . At times there were some sub 1/2 inch groups from the big game and varmint rifles but it could have ben luck helping me.
