[QUOTE="Aussie, post: 128111, member: 2447"] I was assuming you were talking about 50 - 52gn projectiles when I said 3800 FPS . You can drive 40 grainers over 4000 easily . Hot gases are what erode the barrel , not bullet speed or friction . Think there is some evidence that fast , light bullet loads do erode the barrel more quickly but this is probably due to the use of faster burning powder with light projectiles . The difference in barrel life between 40 and 50 grainers in a .22/250 wouldn't be huge . My manual shows a maximum charge of 38.5 gns Varget driving a 40 grainer at 4120 FPS so 4000 should be relatively mild thus extending barrel life . [/QUOTE]
