Hey Sam... You wanna quote your source for the "news" that Remington is discontinuing the SAUM? They just released several rifles chambered for it so I'm surprized.
Also all the loading manuals I have and my actual experience shows from 50-100fps difference in the two cartridges in velocities depending on bullet weights. How 'bout quoting your source on that one too?

My source on Remington discontinuing the 300 SAUM is that it is not offered in their current line. It is replaced with the 300 WSM that they never offered before. Never said that they discontinued all of the SAUMs! Also go to Gunbroker and you will see the 300 SAUMs being dumped while the 7mm SAUMs holding their price.
Hornady manual on the velocity differences and my chrony! The case capacity being larger and that is important because the short magnums fill the cases to the top.
You didn't quote a source except to say that it isn't offered in their "current line". Now you're trying to say that's not what you said? What do you mean by "current line"? I'm not sure what that means but I'll actually quote my source(s).
Titanium
Model 7 CDL
Model 7 SS Magnum
Model 673 Guide Gun
Alaska Wilderness Rifle
Light Tactical Rifle
OK... It looks like Remington offers SEVERAL models, some of them introduced at this years shot show that are chambered the 300SAUM cartridge. I might not have caught them all.
Also your info about them never offering the WSM in their rifles before is wrong. They've offered it for quite some time. You might find, if you did some research on their website, that the Model 700 magnum line is primarily dominated by the Remington Ultra Mag and the Winchester WSM.
The SAUM's are primarily found in the smaller, lighter rifles like the Model 7's, 673's, and LTR's.

Now for your velocity claims.
From the Hodgdon website....
Winchester WSM Data
Remington SAUM Data
If you'll call the Hodgdon techs I think you'll find that this is recent data and it matches that in their manuals that are released every year.
There is almost NO difference in the rounds velocities until you get upwards of 180gr in bullet weight.
Your blanket statements with no references left me and probably a lot of other people confused and I thought I'd recheck my original findings and post references.
If you'd like to quote actual numbers out of your Hornady Manual and exactly which manual it came from then maybe we'll see a wide difference in data between them and Hodgdon but I'd be surprized to see it that wide.
If you'll do that I'll post some figures from the most recent Sierra manual too. A quick glance just now shows that data was shot from a 22" barrel for the SAUM and a 24" barrel for the WSM and that differences are around 150fps. If you allow for the 2" length difference which is critical in magnum cartridges you'll quickly see at least about a 75fps difference accounted for in those two inches and many would say more like 100fps or even 125fps.
My most recent Hornady manual is the Fifth Edition. I see that they've released a new edition since then which is the Sixth and I guess that has SAUM data? Have you checked barrel lengths?
