[QUOTE="J E Custom, post: 480465, member: 2736"] Don't get to hung up on efficiency because in many cases it is both barrel and chamber combinations and not the cases themselves that have the most effect on velocity and case capacity. The 7mm SAUM and The 7 wsm are very close in capacity and velocities are also very close with the edge going to the WSM because it has a few grains more of powder capacity and there for more velocity potential all though not much. Both are great cartriges and are just a matter of personal choice. Remington was the first to come out with the "Short Mag" and Winchester countered with the WSMs and a proprietary powder that gave there cartridge more velocity and as we know Velocity Sells. And now days if you can get 50 ft/sec more that the next guy you will sell more rifles with that chambering. When looking at efficiency what does 2 grains less amount to. In a 1 lb can of powder it there are 100, 70 grain loads and there are 102.9 loads @ 68 grain load (Not much) but a velocity increase of 50 ft/sec is significant compared to 2 more grains of powder. Find a rifle that you like and go with it. J E CUSTOM [/QUOTE]
