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
