I know that Broughton makes a good barrel I am going to ask a couple of questions about the 5c 6mm 8 Twist. I would be using it for a 6mm-284 and I want to know if anyone has been having trouble blowing bullets up with this barrel. I shoot mainly 95 berger VLD's 95 Ballistic tips, 100 Sierra SPBT GameKings and I would probably be shooting the 107 Sierra matchking as well. All of these bullets should be comming out of this rig over the 3300fps mark and the 100gr sierra and 95 B-Tip would be more like 3400 to 3500fps. My old barrel did not have a problem but it was a Hart 9 twist 6 groove.
