So how much demand would there be for 18.6" 50 Beowulf barrels?

[Brian46]

Ruger does an 18.63" ar in 450 bushmaster, that would be a good parts kit for the atrs upper and lower

[Brian46]

We have a potential line on ammunition for the beowulf

any details you can share like available loadings and projected price?

[techi870]

I'd be interested in a large bore barrel.

[GlassLightning]

I'd be interested in .458 Socom, .50 Beowulf, or .450 Bushmaster in that order.


For anyone not wanting to grab a big bore barrel because of the magazine cap limit, .458 Socom uses standard .223 magazines so you can fit 4 rounds in the 10 round XCR-L mags.

TNA also has purpose made 5 round ASC magazines for .450 Bushmaster.

[Big bore dinosaur]

458 socom.. or 458 hammer... would both be great options .
I believe the later of the two has more jump in the chamber, and thicker brass..

450 bush master mags feed socom rounds also

[valk775]

I would buy 2 458's

[TXS]

Yes.

I have a bushmaster ACR. It is chambered in Remington 30AR. It uses a .492 bolt face and a max psi of 55,000.

It is a custom made bolt, I have zero failures to date

i will amend my statement and say that a .473 bolt in an AR15 will not handle the 60k psi of 500 Auto-Max.

450 bushmaster uses a .473 bolt, yes, but it also runs a very low 38k PSI.

30 RAR in AR15s uses a special upper, bolt, and barrel extension that are all larger than an standard AR15, which is how it handles the high pressure of the the 30 RAR.

The ACR uses AR15 size parts, my custom bolt is proof tested at 20% higher than its 55,000psi max load by the builder.

You are however correct, the only factory offering of the 30AR was a hybrid made by Remington.

Mine however is all AR15 size components

[Trump308]

Just a thought, does the upper need to be finished differently to feed single stack large diameter rounds like the 458 socom and 50 beowulf as opposed to say 223?
