I inquired about the BCG and here's their respond:

We use 3 different BCGs depending on which Magnum it is in the Arsenal. The 458 can use all of them. We make one, we have a third party making the 2nd, and the 3rd is a KaK. Due to Youtube's constant policy changes. Linking a site to promote the sale of a firearm is against some of their wording. Just google VA Silent Arsenal. Send us an email. cs@[/COLOR][COLOR=#0000cd]vasilentarsenal.com


I haven't have time to investigate further but on their website it said their webstore will be open in July 2019 guess should know more in a few weeks.

If they can do that, I bet they can do a 35wsm too, that would be super cool! A stag10 in 35wsm would be sweet!

What magazines does these use?

 

[wildphil24]

Their website suggest Larue and ASC mags. So metal mags and you may bend wider the lips if required.

The WSM case is .550" diameter. I'm not super comfortable running that at 65,000 psi with the diameter of the barrel inside the extension. The thread is the same size as a Winchester Model 70. Smaller than Rem 700 or a Savage 110. There have been cases of people/companies running too large of a case diameter at high pressure in the AR15 platform and bulging the barrel at the chamber.

so just don't run 65k psi, like you do with large diameter cartridges on the AR15 frame. 50 Beo, 458 SOCOM, 450 bushmaster are all running 38k or less PSI.

 

[wildphil24]

For those concerns a .300saum would probably be better than wsm. It's a touch narrower and weaker. Plus a better profile for smooth chambering.
The missing link is a good and available bolt for the SM calibers.

I run rem 30ar in my bushmaster acr (ar15 size components) it is a .492 rim at 55,000psi, no issues

These guys are well respected, "only" in 300 Win Mag, but their rifles seem to hold up well.

I think the SAUM is a .550" body. The 300 RCM is .532", based on the 375 Ruger. I was thinking of a 300 RCM Stag 10 . The case is unfortunately a couple mm longer but should still be doable in an AR10 magazine.

The 30 AR has a smaller case diameter, essentially your removing .055 (.0275 off either side) for the WSM case chamber, and then your upping the pressure, so thinner wall pipe AND higher pressure. So, not really an apples to apples comparison.

Especially with the heavy projcetiles, I bet that 458 has the potential for some really high pressure if your not careful in loading/reloading.

The advantage of the SAUM/WSM cartridges is that they will fit in the common, relatively standard AR10.

A 300 win mag "AR" is really a proprietary, custom gun.

The guns we are talking about here only require a special bolt and barrel to convert from an off the shelf AR10.

Have you heard of .475Bishop?
5600ft.lbs of muzzle energy in an AR10!
Almost 2000ft.lbs more than .45raptor!

Wow, that's interesting!

Anybody know who make .475 barrel for AR10?

Where to get brass and dies?

Bishop ammunition. They designed the caliber and guns. 1800$us upper includes a 24" Tactical ordinance barrel, single stack mag, proprietary rifle-lenght recoil buffer, 100 Hawk or Cutting edge bullets, 100 Robertson brass cases, muzzle brake and adjustable gas block.

KaK industries does an Ar 10 in 450 marlin also. Watched the 458wsm on YouTube, real quite
