FWIW, the highest velocity I recorded from any of my 6.5x55 rifles, with 140 grain bullets, was 2930fps (plus or minus fifteen or so). This was from a 26 inch barrel, throated to accept 140 Matchkings, and using 50 grains of VV165. A good load but one which produced over 1 moa of vertical at 900M so I went back to a slower load (2800 fps) using 4831sc. GD
Thanks.
2740 fps, w/ the 140 gr. GS bullet, appears to make a good 350 yd. load.
Am leaning toward the H4831 powder, and will look for a precise load from there.
Calculate 49.3 gr. from a 24" Bbl.
