.25-284 vs 25 Saw

[Marksman LLC]

Which one would produce higher velocities with a 20 inch barrel?

I'd would assume the 284 case has more volume therefore more speed but I don't have much data or information on the Saw cartridges to know for sure.

Anyone have experience with the Saw cartridges?

No experience with the SAW. Also my 25-284 has a 25" barrel with a 1-7.25" twist. I get 3160 FPS with a 131 BJ and R26.

25x284 is going to do what a 25-06 will do but in a shorter COAL. Still would probably run it in a long action though.

You might be able to look for 25 souper data and kinda sorta extrapolate data on the 25saw that way.

Or call Clayton at West Texas Ordinance. I'm sure he probably has some info on the saw offspring.

I do not have experience in both, but as you noted, depending on the source, the .284 Win (66g of H2O) case has the case capacity advantage over the 7MM SAW (parent case 7MM-08). 7MM-08 has 52g of H20. The 7MM SAW will have more capacity than its parent case (https://westtexordnance.com/7mm-saw/).

I had a 25/284 on a Mauser 98 action to allow me to utilize the added case capacity.
I still have a 25 Souper AKA 25/308.
I also have a 257 Roberts and a 25/06.
I sold my 25/284 as it really just matched a 25/06 and brass is so much easier to get for a 25/06.
I also prefer a 257 Roberts over the 25 Souper.
In a modern rifle I would think you want a short action to take advantage of the 25 Saw.
My favorite 25 cartridge is the 257 Roberts even though it gives up 100-150 fps to the 25/284 or 25/06.

What bullet/s are you looking to run?

What bullet/s are you looking to run?

Mostly 133-135, and maybe 145 grain.

My guess the .25 saw wouldn't push the bullet fast enough in a 20in barrel.

Have you looked at the data on the WTO site?

25 SAW Cartridge Development – West Texas Ordnance, Inc. | Custom Rifles & Accessories

I'm trying to decide what 25 cal to build on a short action and the 25 SAW is in the running for sure.

Mostly 133-135, and maybe 145 grain.

Between the SAW and the 284 I'd go 284. I am toying with the same Idea, but on the 6.5PRC case.

I have a .257 WBY 22" 1:7" specifically built for the heavies.

The current load above has 145 Black Hole bullets.

How are the black holes shooting?
I have 500 of them waiting for load development on a 25 creed that ill be getting back any day now. If I can get 2700 fps mv out of them ill be very happy.
