how does the 300 WSM compare to the 300 SAUM?

The WSM has a future, the SAUM doesn't.

I prefer the SAUM over the WSM...

When you reload, the SAUM brass will last way longer for the 300 SAUM because of the angle of the shoulder...

A friend have a WSM and after only 3-4 shot with the same brass, it's over, the brass is cracked.. With My SAUM, I have some brass fired 4-5 times and no sign of deterioration. My brass will last for minimum 15 shot each...

I like the design of the SAUM better, but the WSM will be around longer I'm afraid.

...and of the two, I most like the 300rcm..

I have a 300WSM in a M-70 Coyote. When I work up a load, I use the same 6 to 9 cases over and over until they split or won't hold a primer anymore. Looking through my reloading data, I have reloaded my current 6 cases twelve time each. One of the quirks I have with my particular rifle is that I have to full-length resize the cases on the third reloading. Even so, I have not had any case seperation what so ever. Apparently my chamber/head-space is on the money.

Your friend is doing something way wrong. WSM brass is as long lived as any I have ever seen--period. Having experience of 4-5 rounds of reloading is nothing. I have WSM brass with over 50 reloads through it.

The SAUM is toast, and mfgs continue to chamber for the WSM's and components are readily available. The 300 WSM in particular is more potent (powerful) than the Rem version.

What fish30114 said. I have no experience with the SAUM's but I do have a .270 WSM that I handload for. I haven't counted the number of times some of my cases have been reloaded but I'd guess that I've got some that have been loaded about 12+ times. Maybe more. Have yet to see any case splitting or cracks. Frankly, I'm surprised at that.

Those cases than have been reloaded so many times --- have you ever annealed them?

I have 300 WSM brass that was loaded ten times before they needed to be discarded. The same is true with the 270 WSM, the 7 mm WSM and the 325 WSM. The brass lasts for a reasonable amount of time, provided one doesn't load hot.

DB Bill, I presume you are asking me about my WSM brass, and the answer if you were asking me is yes.

I anneal after about every 8-12 firings, just depending on the brass, this is not unique to this rig, I have a lot of rifles, and 6 or 7 WSM's. I have GREAT brass life with all of them. I use the Forster Bushing-Bump die whenever I can, which provides absolute minimum working of the brass. Having said that, they don't make one for 270 WSM, and I don't use a neck bushing die on that brass, I just PFLR setting for about .002 shulder setback.

I do sand down the expanders on my dies for minimum working of the neck as well, but my WSM brass just hangs in there for a long time before I feel the necks getting kind of stiff when I size, and the next time after I feel that, I anneal.

A .308 diameter, 180-grain bullet with a muzzle velocity of a little over 2900 fps, is a .308 diameter, 180-grain bullet with a muzzle velocity of a little over 2900 fps, whether it's fired from a full-sized .300 Win Mag, a .300 WSM, a .300 SAUM, a .300 H&H Mag, a .308 Norma Mag, or the new 300 Ruger short magnum. Redundancy in performance is the name of the game when it comes to .300 Magnums.

More important than the cartridge being fired, is the rifle and action it's being fired in. I prefer CRF actions, so I would opt for a full-sized Win Mag (which I can load up to 3100 fps, if I so wish) in a Winchester Model 70, or the WSM in a Model 70. (Ironically, I have both a .300 Win Mag and a .300 WSM, both custom rifles, and both built on Remington actions. I like them both, but were I to buy an off-the-shelf rifle, it would be the CRF, Pre-64 style, Model 70.)

There aren't any of those! Especially in a Short Mag--of any designation---there are current production style Win CRF rifles though, and they are better from a safety standpoint than any pre-64.

The operative word(s) being CRF, the new Model 70s are just fine with me, as are the Ruger M-77, Mark IIs.

But, as I said, when it comes to .300 magnum performance, it's whatever floats your boat!
