[QUOTE="Outlaw6.0, post: 812632, member: 23486"] Without bullet weight & powder type the question may be somewhat subjective. A heavy bullet & slow burning powder will extend the life of the barrel significantly. A 55 grain pill & fast burning powder has the ability to torch a throat relatively quickly.
