[QUOTE="Fiftydriver, post: 60747, member: 10"] I would agree somewhat with Goodgrouper on his comments. At least as far as heing harder in thin jacketed match bullets. Of course I have only noticed this with fast twist barrels. In standard twist barrels I have shot the J-4 jacketed bullets at extreme velocity(4100 fps with a 100 gr) with groups in the .2"s and .3"s in my 257 Allen Magnum. Lilja says they are faster then a standard 6 groove and I tend to agree but to what extent it is very hard to tell. Perhaps 30 to 40 fps at the most. I have found they foul less then a 6 groove and barrel life is also significantly longer. THis is why I use only Lilja 3 groove barrels in my 257, 6.5 and 270 AM rifles and any other extreme performance rifles I build. Again, I have found that a 3 groove will tear a match bullet up very quickly in a fast twist barrel. Much quicker then a 6 groove. Good Shooting!! Kirby Allen (50) [/QUOTE]
