I am a very poor group shooter and can,t do a good gun justice. For some reason the one exception is my 6.5x55 mauser. It is a surplus rifle and still wears the military stock. I had the bolt handle bent and had it drilled and tapped for scope bases. I also installed a Timney trigger. The trigger is set at about two lbs and there is no felt movement during the trigger pull.The bore in this rifle looks like new. My first load was with 140 grain Hornady bullets. The group was a bit under 5/8 of an inch and I have never changed a thing since. I sight it about 2 1/2 inches high at 100 yards. It has a thirty year old Redfield 2x7 tracker scope on it. My loads chronograph at 2760 fps. I think the secret of it accuracy is the weight of the rifle, the excellent trigger and the exceptional accuracy of the caliber itself. All of the Sewdish mauser bores I have looked at are like new.
