In my 1939 vintage Stutzen I use Vihtavuori N140 powder to very good effect. I find 38.0 grains is fine with the Sierra 140 grain Match King bullet (for targets) and I also have some ex-Canadian Dominion 160 grain soft nose bullets to try. These came as loaded ammunition, but the powder had completely broken down and were completely erratic, so I pulled the bullets to reuse them sometime. The 140 grain bullets do not feed that well, but the longer ones work perfectly, of course.

The set trigger takes some getting used to; I have managed to get the pull weight UP to about 8 ounces...
