Glad We have the numbers to compare. I do not think Id feel at all compromised with a 100 grain Interlock BTSP or Berger 108 gr Elite hunter SD @ .242 & .261 BC @ .405 & .559 respectively. Though Ill be launching these From a 22" Bolt action @ roughly 2800 FPS give or take 50 FPS. Feel fortunate to have a good stock of each of these 6mm bullets in stock. We will see how load work up plays out as to which one shoots best.
