Think I've got a shooter. Took a half day off yesterday to take advantage of a sunny day in No. Calif. Targets are at 100 yards. The barrel had been leading a bit before and on some previous range sessions I ended up breaking in with 50 jacketed bullets and it was still leading a bit so I ended up putting 15 firelappng bullets from Bear Mountain. Leading no longer a problem.
So from an absolutely clean bore the first 5 shots were not that great. About 5 inch group. Next 5 were about 4 inches. Next 5 about 3. Hmmmmmm. Targets below are the 5th and 6th groups. The next 3 were similar. Hmmmmm. Cleaned the bore again and same thing, big groups that kept getting smaller. I think my rifle likes it dirty. Now I wonder how long it will shoot before it gets too dirty. Gee, I guess I'll have to shoot it more.
This just became my favorite rifle. Hell my Lyman scoped 270 Remington 700 doesn't shoot this well.
Had also experimented a bit with powder and bullet sizes. These were all shot with Bear Mountains 250gr GC at .377. Powder is 4759.
