Looks like you're already getting pointed in the right direction. Old Mil Surp's are a real hoot to shoot once they're dialed in with cast... This was my Mosin 91/30 this morning after getting the new scope dialed in. The details: Lee TL 312-160-2R sized at .311 over 13gr. Red Dot at 50 yds. Final group--10 shots. I think it works out to about $.08 a pop for this.
Can't beat it with a stick.
