458 SOCOM AR-15

[babirl]

(MODS: PLEASE EDIT at will!)

458S is also a "growth" round!

Way smaller group than 6.8/6.5/.300 lovers, but I know there are a few .458S owners, along w/ .450 and other "big-bore" AR owners/lovers out there.

I think it would be good to "contain" 458S discussions to here until site is recovered/enough interest generated. Seems I recall at least three 458S threads pre-2012?

FWIW, I know the original 458S Forum got hacked/spammed/denial of service and is slowly recovering: http://458socomforums.com/index.php

It sucked and lost tons of info, same happened to the original 6.8 Forum, and "WE" are nearly the same situation here on CO AR-15... The "good" will persevere and float to the top!

Anyhow, for anybody frustrated getting approved on the current 458S Forum, my understanding is Marty is doing it from overseas/one-by-one/as available.

Hmm, Wilson Combat also just announced a deal w/ Marty and they're now producing a 458S rifle and stand behind it... Look for growth after the Red Jacket idjits on TV talked about the 458S. Regardless, seems it's taken on a life of it's own.

Have you checked out : Beyond556.com ?
Lots of 458 SOCOM discussion in the Big Bore subsection....
I need to take mine out shooting to re-sight it in. I did a site set change.
And I want to see how the 325 gr. FTX and 350 FMJ FN rounds shoot. I have been shooting 300 gr. SNHP and they seemed to group good until my front site came loose, forgot to lock tite it.

Does 45-70 count?

[SideShow Bob]

Only if it is an AR chambered in 45-70.......

Thanks and will do.

(For our real .45-70 brother, the cool thing about a 458S is it's nearly equivalent out of a AR carbine, even a SBR-version if I was so fortunate to own one...)

I haven't shot mine near enough either, but what a freakin' cool option in an AR platform! I'd expect the .450 guys smile just as big, but my heart went 458S just because of the projectile options and especially how/why it was created!

FWIW, I'm "in" @ the new 458S Forum probably because I was on the deceased forum. Anyhow, think we have a few other 458 platforms in the state/area now and would like to help if I can.

Must be getting old and wimpy.

Working up H110 reloads today and 50+ rounds... Seems I have a bit of a tingly shoulder tonight. On the other hand, it was a bit breezy but nearly a perfect day w/ my son.

On a serious note, for ANYBODY reloading for the 458S: ANY Pressure Signs means your in dangerous territory and back off!

It's super easy to cross that boundary, most especially w/ the Barnes TTSX due to it's length making it a different animal. I definitely saw swipes @ 31.0 GR/MAX load... Certainly no need to ever push that projectile that hard.

Definitely a very cool option out of an AR platform and big holes leak more!

More big bore propaganda... They ain't "cheap" but sure are fun:

Seems like fun doesn't come cheap either way, so you might as well get a beast

Wish I can graduate to the big boy club but funds are lacking

[coloradoEMT911]

this will be my next upper i build would love to do a complete gun but prolly just do an upper eto switch out with my .223.

Upper is a perfectly fine option and works well.

WARNING: It will build itself into a lower and accessorized! (It's that EBR thing... This "big bore" AR thing is addictive.)

I have some "special mags" I Dremel'ed half-moons into but not required for most loads. Soon to test are the "Lancer" mags.

FWIW, Wilson Combat is now fully in the 458S game:

(He fell in love w/ the 6.8 and now the 458S for hogs and general hunting purposes...)

Overall, I understand there is a barrel and muzzle device shortage industry-wide... Also, seems to be a shortage of the "generic" .458 300 GR projectiles.

The Barnes 458S-specific is perfect/not-cheap... Lot's of folks helped make it reality.
