Thanks Strapnug!
I have a few cases loaded now, and if this darn snow ever lets up, I'll give them a try.
Do you use original 8.15x46 cases, or reform from .30-30 or similar brass?
I found a set of claw style scope mounts for 1" scope, so I have mounted a old K10 Weaver scope on it for load workup. I'm modifying a long range vernier sight, to adapt to the square hole in the rifle. Hopefully I'll be able to use iron sights for most of my shooting. I built a new base on my mill, for the Aydt base, and made it to fit the upright from my Winchester Hi Wall rear sight. Looks right at home on the Aydt!
