Remington’s answer to Winchester’s .300 Short Magnum is a .30 of their own–plus a 7mm. Officially designated as the Remington SA (for short action) Ultra Mag, it heralds the beginning of cartridges based on a shortened version of the Ultra Mag case.The rationale is of course the same as that which spawned Lazzeroni’s Short Action Magnums and the .300 WSM; namely, cartridges that can ballistically match the now old-fashioned longer-bodied belted magnums, and do it with less powder and in short-action rifles.

In a side-by-side with the .300 WSM we find the Remington case to be 1⁄8-inch shorter in body and in overall length, and to have a 30- rather than a 35-degree shoulder. The result is a vessel of 7.5 percent less volume than the WSM. Nonetheless, Remington is claiming virtually the same nominal velocities for their short .30 as Winchester does for theirs, i.e., 2,960 fps for a 180 gr. bullet versus 2,970 for the WSM.How ‘dey do ‘dat? Well, it’s the kind of smoke and mirrors thing that advertising and marketing guys are paid to come up with. We all know that, all other things equal, a case having 7.5 percent less volume shouldn’t be able to match the larger one performance-wise. That’s not an absolute, mind you, because funny things can happen when you increase case capacity to ludicrous proportions relative to bore diameter, but in this instance we’re talking well-balanced cartridges of moderate (by today’s standards), powder capacity.

7mm saum ammo history

The 7mm SAUM ammo was released in 2002 based on a shortened version of Remington’s Ultra magnum case which is in turn based on the 404 Jeffery’s case. The SAUM was designed to produce 7mm Remington Magnum performance from a much smaller cartridge case and more compact rifle configuration.

In 2002, the same year as the introduction of the 7mm SAUM, Winchester released their own short magnum, the 7mm WSM. The two competing cartridges were presented to the market but only one survived – the 7mm WSM. Not only was the WSM more popular with hunters, the cartridge was soon adopted by several rifle manufacturers, ensuring its continuation.

Case capacity of the SAUM is slightly less than the WSM, as is the factory COAL. Remington adopted these dimensions to enable their short magnum cartridges to fit into the compact Model 7 action. Factory barrel length of the Model 7 is 22″ as opposed to Winchester’s short magnum barrels at 24”.

The 7mm SAUM currently retains a small following. This cartridge, chambered in the model 7 rifle, is appreciated for its ability to produce high power from a small, ultra-light weight platform.

7mm saum ammo performance

The 7mm SAUM ammo does not achieve 7mm Remington Magnum velocities or performance. This cartridge duplicates the velocities of the .280 Remington.

Hand Loading 7mm saum ammo

The most suitable powders for hand loading the 7mm SAUM are those in the 4831, N165 range. Achievable velocities duplicate factory loads including 3150fps with 140 grain bullets, 2950fps with 150 grain bullets and 2850fps with 160-162 grain bullets.

References to bullet performance can be found in the .280 text of which the 7mmSAUM performs very similarly.

Closing Comments of 7mm saum amo

The differences between the 7mm SAUM and 7mm WSM in factory ammunition or hand loads average about 75fps in favor of the Winchester which is mostly relevant to the Winchester’s 2” longer barrel. However it is perhaps moot to draw comparisons between the two because the design concept behind the 7mm SAUM Remington is to offer an effective medium game hunting cartridge in an extremely efficient carbine for hunters who require the minimum of bulk and weight.
