    Just picked up a NIB stainless 700 in 300 saum. Thinking about doing a build off it but wondered if I should keep the saum or go with something different. I already have 7saum.

    None that I can think of.

    The only advantage to the 300 WSM over the SAUM would be brass availability.

    In my opinion, I see no reason to build a 300 RSAUM when you already have a 7mmSAUM. The 7mm will have superior ballistics in just about every catagory over a 30 caliber in the same cartridge. I guess the question is, what are your intentions with this new build? Hunting, target, etc....

    What you need is a 7mm STW.

    Here's a few other gaps I see.....6.5 Sherman, 6.5 SS, .257 Wby Mag, .300 WinMag, .338 Lapua......

    Yep I agree that there may be some ballistic gaps, but I have a 300saum donor to work with and Im looking for a 30cal that will work with my action.

    Pretty much the only thing that will work with that size barrel and bolt and action length combo is .300 WSM or .300 SAUM.....Not much choices I can see with that combo of parts.

    I appreciate the help. The barrel is not relevant. The only part to consider is the action in the build.

    The brass availability for the 300 saum is next to none. Remington has not run this brass for 2+ years with no plans to get it back up and running again. It as great cartridge, so building the gun would be awesome. If you ever want to shoot it......that's a different story.

    The 338 RCM would have been my other choice to your short action build, But you've got that covered.

    The 300 is a good choice and Norma makes brass for it if you don't find any Remington.

    Shame on me for not reading your previous post. I see you already have a 7saum. If you can share the brass between the guns...your in business.

    I have in my possession 2 bags of 100 pieces plus a lot of once fired 300 SAUM that belong to my friend and he has replaced them all with Nosler brass and has no intentions of using the Remington cases.

    Both my brother and him own the 700 SAUM in 300 caliber. I have seen the brass available in the past at my local Bass Pro. Here's the problem: RP brass is junk in my opinion. I've been doing all of the loading for both of these 300 shorts and the primer pockets are loose many times in once fired brass. I like the caliber itself but it has turned out to be less than impressive to me.

    My brother just mailed me his last 40 once fired cases for reloads as I will be hunting with him in just over 2 weeks. I had to pitch 9 of them as the primer pockets were so loose the primer could be manipulated after it was seated. That's ridiculous. Second, I loaded 150 nosler Btips for him. Can't remember powder or charge but the published test barrel is also 24" like his and these will only be going about 3050-3100 fps. I'm getting 3050+ with my 270/150 VLD loads from a 24" Krieger.

    The book says he can get a few more fps but then accuracy spreads when we tested these last year.

    For a build, you can add tube length and compensate that way, plus use a bit slower powder but if you want this brass I will let my friend know.

    I think I would phrase the question... Is there any reason not to build a 300 WSM?

    Although the 300 SAUM is a good cartridge, the writing is on the wall for the SAUM's. Remington has stopped producing them and brass is going to become more scarce.

    The WSM has more case capacity and brass is readily available. Why would you not build a 300 WSM? That's my question.
