[QUOTE="Stokesrjsr, post: 1691331, member: 108548"] I’m not a PRC competitor but from many years of NRA High Power Rifle Competition I’ve seen dozens or maybe even hundreds of mid flight bullet failure. Although usually it isn’t a white puff but a blue one. This problem is what drove Berger to introduce a thicker jacket on what is now called the Target VLD and the hunting VLD is the original thinner jacket. The most common cause was not an excessively fast twist, although I herd it commonly blamed. The real culprit turned out to be excessive carbon build up at the throat. I learned this after purchasing a Hawkeye bore scope and then examining barrels that had suffered this match loosing trait. It usually happened only once in a 50 or 80 shot course of fire but in more severe cases it would produce multiple blue puffs of death. The problem was easily resolved by polishing the carbon away with JB bore compound. [/QUOTE]
