[QUOTE="Bart B, post: 624653, member: 5302"] It's important to realize that if one's rifle using these cartridges starts out with less accuracy, its barrel life will tend to be longer. That's because barrels starting out wil less accuracy take longer to notice when they open up 25% to 50%, A factory rifle for one of these cartridges starting out at 1 or more MOA at these ranges may well go 2 to 3 times as many rounds of barrel life. Note that to me, accuracy is the largest many-shot test group fired. That's what can be counted on all the time. All those micro-measured single few-shot groups are the smallest percentage of all groups fired. [/QUOTE]
