[QUOTE="sable tireur, post: 1496061, member: 27307"] Simple fluid dynamics (or plasma dynamics in this situation), take your garden hose and open the sprayer all the way up. The stream of water is slow and low pressure at full volume. Now turn the sprayer all the way down to the smallest orifice and the pressure surges up and the stream has more force. There is a [U][I]general [/I][/U]rule of thumb which gets applied to reloading. The smaller the caliber in a cartridge case, the slower the powder necessary to achieve proper pressure. The larger the caliber in a cartridge the faster the powder can be to achieve the pressure. In essence, your 6.5-300 Weatherby functions at pressure with a slightly slower powder and your .300 Weatherby uses powder a step or two faster than that pressure range. [/QUOTE]
