[QUOTE="elkaholic, post: 2347541, member: 13833"] No idea yet on barrel life? With the number of firings on the case so far though, Im not at all concerned about what the pressure number is! Guess on barrel life would be 1000-1200 rounds based on the 7 SS and 7 Max. It would be better with powders cooler burning than N570, but velocity would be lower. Here is what I know so far: This barrel had 300-400 rounds through it as a 7 max running mostly 570 and has around 250 more as a MEGA. It hasn't been scoped but shoots .2 at this time with no drop in velocity. Not all that meaningful, but what I have to date. [/QUOTE]
