Hello all, Those of you guys/gals who have done this kind of shooting, could you give me feed back on this cartrige for 1000 yards target. I realize there's better but I am thinking that perhaps this round won't kick as much as say the 6.5-284 or 308? Plus I am also hoping it won't be a barrel and throat burner. What about the .223 shooting 75-80 grains bullets? What twist will the barrel needs to be? 1-7 overkill or 1-8? I hope to have lots of feed back as I have caught the bug after this past week end where I attended a shoot at Tulsa Red Castle Gun Club. Thank you for your time.
