[QUOTE="Bart B, post: 625685, member: 5302"] That's an interesting table. Too bad it doesn't show how much powder's used for each caliber range. The more one burns for a given bore diameter the shorter the barrel life will be. The best thing about it is the results for very slow powders. All the rest is misleading. And one post in that thread claims a barrel with 20,000 rounds through it still shoots 1/2 MOA. The author doesn't mention if that's the largest or smallest groups it now shoots. I doubt either is reality unless it's a .22 rimfire match barrel which these days will go 30,000 rounds of sub 3/4 MOA accuracy through 100 yards; maybe his is an old McMillan one using pre-1983 Eley Tenex match ammo.
