The 223 Remington Howa 1500 thumbhole varmint rifle has ben one of my best buys. It shot sub one inch groups out of the box with 50 Gr bullets. After my first test groups I glass bed the action, free floated the barrel, and adjusted the trigger pull down to 2 3/4 pounds. I now get 1/2 to 3/4 inch 100 yard groups with reloaded ammo. I have had other brand rifles that took one or more of the following to get them to shoot smaller groups. Glassbed the action, freefloat the barrel, adjust the trigger pull,lapp the bolt locking lugs, recrown the muzzle, remove wood from under the bolt handle, and free float the magazine box by glass bedding the trigger guard. I got my first rifle in 1949 and have learned that with any brand fire arm you dont know what you got untill you shoot them.
