Yeah, Someone always has to bring up "barrel burner" referring several of the cartridges that's mentioned on this forum. The fellows running top fuel dragsters don't worry about tire life. The guys running Honda Accords do expect long tire life. Go figure.I always get a kick out of the ""man its such a barrel eater"" simply the worst comment ever considering the barrels are made too be taken off and replaced. I've built several and they are ridiculously accurate .. 127 LRX is bad SUM B as well as the 156 berger and 140 accubond ...haven't had much for troubles with them as far getting them too shoot or great accuracy.
