Loaded up some loads with AA2700 and rem 9 1/2 primers behind a Nosler 55gr BT 43.o and 43.5 out of my Win 28" bbl 1885 . Sweet tight small groups immediately. Thought I try same load behind some 53gr V-max becuase I know my bbl is a 13" twist rather than a 14" and they only shot fair at 100 yards. Looks like I'll be buying a 8lb keg of that stuff. Didn't have time to set up the Chronograph .
