20” 30 caliber short mag, 300SAUM, WSM or Sherman Short

[Mike D Texas]

I see a short, light 30 caliber short mag in my future. What is the best option for brass availability, performance does, etc…?

I want this on a short action and would like to push 178-208 grain bullets over 3000fps.

Is that even doable and which would get me there the easiest without beating up brass and the rifle?

Quality brass is high on the list of importance. This will be a low volume shooter I'd it matters.

Looking for recommendations on the most well rounded package taking all of the above into consideration.

300 SAUM

300 SAUM

That's the way I'm leaning since I'm already building a 6.5 SAUM with some improvements.

Just waiting on my receiver from Pierce Engineering @Jud96 .

Good luck with your project build, and have fun with it.

IF you can find ADG 300 WSM that would be my first pick!

 

[Mike D Texas]

Hmmmm, I just saw where ADG will be making 300 WSM brass.

We should receive a bunch later in the year, but we all know how that goes!

From the looking I have done, 3000 fps from any of them on a 20" tube with a 200+ is gonna be beating up brass. I'm building a 20" long throated 30 nosler, and plan on 208's @ 2950-3000 fps, any more and I'll consider it being blessed by the velocity gods. However, 178's at 3000 should be plenty attainable!

That changes things, but "I" would go with LA instead IIWY unless the PE SA can provide you COAL in the 3-inch plus range, but that's just me. Cheers!

Playing around in Quickdesign, on a 300 SAUM with a 178 ELDM I can seat it at 2.930 and have the bearing surface above the neck/shoulder junction which would easily work in a SA.

Hornady 10th edition manual is showing 2900 FPS out of 24" with 2.755" already for the 178 ELD-M. With the right powder, 3000 FPS is attainable, esp. with a 26" plus barrel. The .300 WSM might still be worth exploring, though.

I went with the 300WSM on an XM action 20" barrel because of ADG brass availability. Quickload has a 205 Berger at about 2700 w/ RL26. Gun is still being built. The Shermans have brass availability as well. Most of my decision was based on component access. But I'm like you. I just HAD to have a short barrel 30 cal.

Lighter bullets and even lighter hammers will probably get you over the 3000 mark.
