Best thick bush round?

[Goshawk]

Can't stop giggling everytime I see these photos

Has anyone got a rifle in 458SOCOM?

Think its a worthy round for Australia?

[Goshawk]

I sort of want one......

hate to use cliches... but its a solution to a problem we dont have in Aus...... a 45 cal running at win mag velocities is too slow

[Goshawk]

I like the fact it uses a standard 308w bolt and magazine. Short barrel version with red dot scope would be a fun scrub lead brick thrower.
A 338fed would be a better choice as it would allow for longer shots

The 458 socom is one of the best subsonic cartridge available. It stays stabilised out to a 5-600m and has enough energy at that range to be man lethal. It's a special purpose round developed for military.

For target shooters, the transition from supersonic to subsonic is a major source of inaccuracy because the bullet destabilises as it goes trans-sonic then restabilises. A cartridge that doesn't go transonic can be inherently accurate. This cartridge is very interesting to benchrest shooters shooting out to 600m as it won't go transonic.

I'd say it would be a fairly expensive cartridge to run. 50AE brass isn't very common, 300-500g projectiles won't be cheap.

Bit confused here; subsonic stabilised to 600m or supersonic through to 600m??

The BC of these light 450 projjies is ordinary from a BC of 0.23(325gr) down to 0.175 for the 250grainers (Hornady examples) in other word they fall out of the sky type of thing... the drop to 600m if subsonic would be stupendous.

There is a guy how shoots one in Canberra out to 600m. I think he uses 500grainers. No doubt their would be heaps of drop, but it's a known variable and therefore you can adjust. From what he said they don't go supersonic and maintain their energy out to 600m so well that they are still stabilised all the way to 600m.

Compared to a 223 that looses enough energy they usually don't stabilise out to 600m unless using very fast twist ratios and long projectiles. BC isn't a big concern with subsonic target shooting.

I remember where they decked out an AR in that and a night vision scope on sons of guns as a "hog gun"

[yoshie]

That the other thing that makes it good in the US as it's is adaptable to the AR15. It used standard mags and a common bolt head size. I think it would be fairly handy in a 7615

Wouldn't 300 Blackout do all the same things you outlined above and 1/3rd of the cost or whatever?

[Tinked]

...the drop to 600m if subsonic would be stupendous.

Put a 500gr with subsonic muzzle velocity into the calculator... 641" drop at 600m

[sha]

Run out of adjustments much?

MORTAR -- INCOMING!!!!

Ba hahah ha

[Sakoh]

The large calibre / low recoil rounds really seem to be getting a following lately.

Confused...

[gherx]

In all seriousness, what where these things developed for?

Instead of .458 Socom why not just shoot a .308 or something? With the much smaller bullet the recoil will be less but will shoot flatter and perform the same if not better?

Same for 300 AAC blackout. Why not shoot a .243 or something suitable?

I dunno what the numbers are must there must be a balance, a tipping point where you're better off shooting something lighter faster?

[Lorgar]

I dunno the history of the .458 but can tell you a little about the 300 AAC.

To start it's a military cartridge. Not a hunting/target/civilian cartridge. Basically they're a balance of stealth and an acceptable level of power.

5.56×45mm NATO and 9mm were/are both popular subsonic cartridge which can be suppressed, but don't hit hard enough for what they wanted. They need to be sub-sonic because even if suppressed a supersonic round still makes the ballistic crack, so they can't just use high-velocity ammo to get more power.

So, they used a heavier .30 cal pill to high harder while than the lighter options while remaining subsonic.

It's a bit of a fad in civilian shooting IMO. No reason I would ever want one, but anyway...

I don't really know the .458 SOCOM history specifically, but I expect it was made for more or less the same reason.

[gherx]

Cool, thanks Lorgar.

Yeah basically designed for the same thing. The blackout is fairly limited in range (man lethal) the 458 is a longer range version of the same idea.

[Lorgar]

Yeah, inside 200m is what it's intended for in a military setting I believe?

Ohh Yeerrrrr 300Blk and it'll cover that 200M with about a 18" drop with a 210 Berger!!!! Dont know if you've seen what a 200 grn Berger does to a pig at 100M but it is very effective!!!Here in the Bannana Bender State we don't have Public hunting Access like you Southern Boys and as property's reduce in size these will indeed become more and more popular as time goes on,Basically a Giant .22 shooting 30 cal pills at 1\2 " MOA bloody accurate little buggers!!I love'm but I always was a little Different!!!

gherx

Never Going to happen!!!!! Whats suitable about a 6mm-308????

[Lorgar]

I could be wrong about it being 200m. Maybe it is 100m?

If I bump into a US Navy Seal any time soon I'll ask him for you

I'm with you on just shooting a different calibre instead.
