[QUOTE="heatseekins, post: 107934, member: 4030"] How far do you want to shoot? I have built .308's with 24" rock barrels that shoot 2780 - 2810 with 175gr smk's. You can always start at 24" which is a nice length and cut it down until you get your desired speed and you will have your optimal length. I have been seeing 75-100fps faster bullets with a rock barrel. More than likely he has them in stock too [img]/ubbthreads/images/graemlins/smile.gif[/img] I use 44.5gr varget, lapua brass and fed primers. see the rock customer service thread for group pictures. all barrels are his 11.?? twist. glen [/QUOTE]
