[QUOTE="sandytye, post: 288808, member: 8823"] I have been having a perplexing problem with my 6mm-284. the barrel is a pac-nor 7 twist. The problem is that the bullets are coming apart in midair about 50 to 100 yards from the muzzle. however not all the bullets come apart. it seems that after the barrel warms up with 10 or so rounds thru it that the bullets start to come apart. barrel only has 250 rounds thru it but was doing this from new. I had a smith inspect it with a borescope and everything looked good. the first bullets i used were berger hunting 115's then 105 amax then 105 wildcats and now i am having better luck with 107 MatchKings. also some berger 115 match are on the way to try. I had the bergers loaded down to 2800fps and still had the problem. The 107MK are at 3100fps and i am still loosing 15% or so. I emailed Pac-nor and they said that conventional bullets will come apart between 280,000 and 300,000 RPM. Yet i hear of people using 6 and 7 twist barrels that are not having any problems. Is there something that i am missing here? any help would be appretiated. Tye [/QUOTE]
