I know performance why they are similar. I’m looking to build one of these on a short action so which one would you choose and why between these too. I’m leaning towards the saum slightly but not totally set. Not interested in the Sherman line due to lack of support in Canada and price. If the blackjack had brass I’d consider it as well
25 saum vs 25 prc

Just a thought but what about a 25-284 instead?
No need for a mag bolt face action.
Necking down Lapua 6.5-284 brass would be an easy peasy one pass through a 6.5-284 or 284 bushing die.
Getting Lapua 6.5-284 brass will not only be better quality but be wayyyyyy easier to acquire than finding SAUM or PRC brass.
The case capacity of 6.5PRC is 68-68.5gr H2O and Lapau 6.5-284 is 66-66.5gr H20 so case capacity is nearly the same for all three. I have a 6.5PRC and that is what ADG and Hornady brass measures for case capacity.
If this is being built on a Rem 700 or one of the 700 clone actions you can have a Wyatt's outdoor "Baney" mag box installed and that'll allow you an OAL of 3.100 with very little modification. Even with the SAUM or PRC you'll want a 3.00 box so why not go with the Baney box to allow 3.100

Honestly it sounds like a great choice but I’m just not interested in it. I’ve been wanting a saum of some flavour for 3-4 years now. With adg brass being good it’s finally made it’s way in to the top runnings. The prc doesn’t quite peak my interest as much but now with Lapua brass coming it’s definitely brought itself in the runnings again as well.
One thing you have to love about options. There's a ton of them. Personally I prefer the .284 parent case. Always have loved it. The SAUM/WSM are others that appeal to me also. PRC is another great option. Again, there's so many out there that the sky's the limit.
I am building a 7mm SAUM now on a 700 SA, but will be building a 25 SAUM in the future. Mostly because I have a bushing die to reduce the cases. The SAUM gets you a bit more space, mine is being built with Wyatts new PRC box to get 3.235“. Personally after buying it, I could have went with the Baney. I am testing the 155 Hammer Hunters but will also shoot 168 HVLDs (Have a 28 Nosler for heavies). Now in the 25, I am jonesing for the 135 Bergers. I grew up shooting a 25-06.
That said, pick one and don’t look back. Not much difference between the two. Other than the current shortages, there is good brass for both. Good luck and enjoy your choice.

Isn't that Wyatt's barney box designed for 3.100" OAL max ? Not sure you'd make that measurement with the 131-135s.

The "Baney" box allows up to 3.100 OAL and requires a fair bit less action modification than does Wyatt's mid length kit which allows 3.200+ OAL but with quite a bit more modification to the action and will mostly only work modifying a SA Rem 700 only not the 700 clones. The Baney box will work with just about any Rem 700 and 700 clone actions. With any of the short mag cases the 3.100 Baney box should be plenty of OAL.

Unless you already have it in hand just getting any ADG saum or prc brass will not be easy. Lapua prc brass will be great but it's not supposed to be available till maybe around July and I'm guessing it'll get bought up at a record pace.

With having so much 6.5-284 brass, it was a no brainier. If I didn't go 25-284, it'd have been a 25-260. I have lots of .260 brass also. Something that can run roughly 3000-3200fps is kinda my bracket of performance. I think I can find accuracy between those numbers
im just trying to keep head stamps to 1 gun that’s all. I debated trying a 25-260 or ai but currently running a 260 and dont want to mix brass.
I believe with blackjacks original reamer you can feed in a true short action with the 131’s, which isn’t ideal but they still achieved good numbers. So with a 3.1 it should be totally double
25-260, 25-243, 25-7mm-08, 25-308 any way you look at it, it ends up the 25 Souper.
Unless your changing shoulder angle, headspace, or neck length.
I never got bushing dies for any of them, so would have ended up buying yet another set of dies, and extra bushings.
And i can understand the whole headstamp issue.
When i built my 284, i searched & got 284 brass.
I'm using 7X57 Mauser brass for both my 257 Roberts, and AI.

I definitely can understand that issue as well. Having a few variants using .284 brass, keeping it separate is often times tough to do. Luckily I can fairly easily tell 6mm from 6.5mm from 7mm cases. Telling the .257 from the 6.5 will be much more difficult without putting calipers on the necks. More than likely I'll be using an epoxy marker to place dots on the cases color coding the .25-284 brass.
Just not a savage guy lol
