I bought this 1972 Savage 110 223 in 2013 for $240
I put a Lothar Walther barrel on it, different recoil lug, different stock, different paint, different cheek rest, different bipod, different bolt handle, got rid of barrel nut system, no turn neck 223 reamer, etc.
First 5 shot group from rifle at 100 yards.
It shoots a lot better now.
Not because the barrel is stress relieved and lapped in Germany.
It is because the barrel is so heavy and clean, and the scope is more powerful.
The stress relieved and lapped expensive barrel means it will stay clean longer, and warp less when hot.
