[QUOTE="Bart B, post: 624482, member: 5302"] .264 Win. Mag. lasted 640 rounds. Three .30-.338 Win. Mag. barrels lasted about 1200 rounds. The 26 caliber one was a sub .6 MOA rifle at 600 yards, sub .8 MOA one at 1000. That's what the best match bullets available back in the late 1960's would produce. 30 caliber ones were/are sub .4 MOA at 600 and sub .6 MOA at 1000. I know of no 26 or 30 caliber rifle producing 25+ shot group accuracy at that level burning 65 + grains of powder doing so for more than 1300 rounds. Of course, there may well be some that'll shoot smaller groups with fewer shots once in a while (but there's other groups that are much larger) and have more barrel life under those conditions, but for long range high power competition, you gotta have good accuracy that lasts for at least 25 shots fired a minute or so apart.
