I dialed in my 1980 Glenfield 30A 375W re-bore today. The rifle wears a Weaver 2-7x32 scope. My pet load is Jameson brass, 200gr Sierra FNSP, and 35gr H4198, loaded with Lee dies and Lee FCD. Range distance was 100 yards on a portable shooting bench.
I also shot some Winchester 200gr factory loads for point of impact comparison.
My pet load (#3) group size was 1". The factory load (#4) group size was 2", for 3-shots. I adjusted the scope right 2 clicks after group #3 with my pet load, then shot the factory load.
Shot groups 1 & 2 were two shots each to foul the barrel and adjust the scope.
The Hodgdon web site puts my pet load at 2288 fps out of a 24" test barrel. It's their starting load. I haven't clocked it with my chronograph yet. My rifle has a 20" barrel.
