I've been playing with 3 older rifles a pattern 17 Remington that's 102 years old, a 1943 A3 03 Smith Carona both in 30 06 and a 1944 model 96 Mauser in 6.5 by 55.
All these rifles exhibited the ability to produce 1 1/4 to 1 1/2" groups at 100 yards as long as it was 3 shots. However 300 yard groups were just plain awful, 6" plus. The two 30 06s have 3 x 9 Leopold scopes and the Swede has a Bausch and Lomb 3 x 10, older but adequate for 400 yard hunting.
As back burner jobs these projects are fun. It turns out that the problem for all three rifles was stock bedding and a lack of a pressure point for the barrels. A little bedding on the actions and applied pressure near the end of the forearm did the trick. Now the two 30 06s print at about 3" at 300 yards. The Swedish Mauser with its stepped barrel had the best improvement at 2 3/4" groups at 300 yards.
