Has anyone had experience with the Barnes match burner line of bullets. Looking at the 69 gr .224 bullets and just wondering how their quality control and tolerances are compared to the sierra matchking and/or bergers. Have they shot consistently in your gun? I realize every barrel is different, just wondering if I should even bother trying them. Looking for something that can each out to 800 yards out of my 9 twist for target and to 500 yards for coyote.
