After owning (3) 280 rems 700ks weatherby lightweight and a ruger no 1(26" barrel) the closest any would come to published specs as per Nosler # 4,Hornady or any other handload data for that matter was the Ruger with a 26" barrel 3000 fps(140 grain ballistic tip) the others were pathetically short of this in most cases 200-300 fps difference...Federal 140 grain Trophy bonded HE loads only produced 3070 in any of the 24" guns... I don't know where those velocities come from but I sure have not experienced them....
