[QUOTE="MagnumManiac, post: 2382791, member: 10755"] How has the capacity difference been determined? If you have only weighed the cases, then filled with water and used fired and new, then this will not be acceptable. In all of my 300WM, H1000 tops out at 79g as absolute max pressure. The velocity of this across several 300’s is NOT predictable. I have pressure measuring equipment and the adage that speed equals pressure is not absolute. If it was, then HBN coated bullets would be just as fast as regular non coated bullets at the same pressure. Bore smoothness, number of grooves and other factors, not just pressure, determine muzzle velocity. Cheers. [/QUOTE]
