I am so spoiled with a bone stock (except for bedding) 1965ish 700 BDL 6mm. It shoots 80gr TTSX's 1" higher than 95gr NBT's at 100 yards, and both under 1". I can't bring myself to change a thing. I think it's a 9 twist.

Faith and love of others knows no mileage nor bounds. That's simply the way it is.
