This question came up after a phone call from my pops. He decided he would head out to Colorado to join me for an elk hunt before he is not able. He is sneaking up on 75 years of age and I want to steer him towards something he will be able to shoot for a few years.
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
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.
