Tom, Thanks for the tip. I had checked and found the magazine box needed to be reduced a bit in height. I also lapped the crown a bit and slugged the bore. Just returned from the range. The first two 5-shot groups were 2 1/2- 3", not too bad for open sights, but the next two groups opened badly as the bore fouled.Accuracy is adequate for hunting. Ten shots would probably suffice for ten years the way things are going here nowadays. Still, I'm tempted to see if firelapping using only fine grit would reduce the fouling problem.PS: Today's loads were RE-15; groups were slightly better than with 4064.
