The best i can relate is , the 130gr Barnes TSX in my 6.5x06. 24" bbl, 1/8 twist . Using Rel 22, I get 3120fps, under 1/2" three shot group. For years I have been taking my elk with a 260 Rem. & the Barnes 120gr at 3039fps. Last season tried the Badlands 6.5, 125gr in my260 Rem, & took my elk at under 35yds. One shot, & down. Year before that I used the Hammer 121gr. They all work.
