[QUOTE="Lefty7mmstw, post: 1133194, member: 48043"] So much of the barrel life question is up to conjecture. I've heard (and seen) that stainless barrels can last a bit longer than c m barrels do. I think individual steel has more to do with what you get though as I did loose one stainless barrel rather early. I've read that light for caliber should help bore life as the dwell time in the barrel is less. You are only getting a couple of seconds total bore life while it is under pressure. The two biggest variances that can be controlled are shot speed/heat and cleaning care. If you take your time as to not overheat your barrel, the steel will not give as quickly as it is more resilient to powder blast erosion if it is cooler. Keep your barrel clean and don't beat the snot out of it doing so. The soot may or may not actually be abrasive, but it will sure pack in and ruin accuracy eventually. Mild loads will help a lot too... When the 204 ruger was designed, they found the bore life doubled when the pressure was dropped from the mid 60 Kpsi range to the mid 50 Kpsi range as it runs.
