It's an ar 15 platform with ballistics like a 45-70. People are calling it the replacement for the 223 for hogs?? Anyone got any info on this? I believe rock river arms makes one.

If you can find ammo it would be a great hog round

Rock river makes one. It is an impressive round for sure. Been out for a while...Academy in round rock had some the last time I was in there. Not a cheap round, but great hog round. Thinking of doing an upper in it.

Great round, several years old, ammo is VERY hard to find! I looked at it a few years back, and went with the 50 Beowulf. Bought 200 rounds of brass and it uses .50 cal bullets like the 500 SW, 50AE.

Would this be a good reason to get into reloading? Or not worth it?

Reloading is always worth it in my opinion. As long as you have the time and can afford the up front costs. You will generally get a better product at a reduced cost.

I built a bolt action suppressed rifle for this round. I have never bought commercial ammo for it because of the cost. There are plenty of bullet options in 458 designed for the 45-70 or the big game rifles. My reloads cost roughly $0.60 each using 405 grain soft points - running at 1000 fps its hard hitting and quiet.

How does the reloading process happen? I have never tried it but might want to for this round

Is that initial cost? Or cost of reloads after you've acquired your brass and are reusing it?

Plenty of threads talking about beginning. Typically costs around $300-$400 to get started

A guide I hunted with recently claims to reload sub-sonic .458 SOCOM with homemade, unsulfured black powder and 450 grain cast lead bullets from an old .45-70 mold. Says you don't need the sulfur with a primed cartridge. Anyone know anything about that?

Not counting the brass in the cost. The brass cost is $0.70 - $1 each. I use a single stage LEE press, you can get into a decent single stage press kit for $100 and start making rounds.


My load is a Remington 405 grain soft point over 15 grains of TrailBoss and a Winchester Large pistol primer.

Right now it's hard to find any .458 Socom ARs or parts to build one and even the brass is hard to find. The barrels seem to be in very short supply. I have been looking for things to build my friend one for quite a while.

Does anyone have one available?

Understood....

$100 for a press, and $50+ for dies, plus shell holder, scale, primer, etc. makes it hit over $200 pretty quickly. Then there's calipers, trimmers, etc.

Not being argumentive, just realistic.

458 is more for reloaders. 50 Beowulf will have more off the shelf ammo available. Ammo is not cheap for either.

$100 for a Lee Kit (press, scale, powder dump, and hand primer) + $30 for Lee dies + $5 for a case trimmer is really all you need. It beats paying $60 for a 20 round box of ammo.

Actually I like the 450 bushmaster for crossloading with 45APC (as long as you know which bullets to buy).

You can get the single stage press for 30 bucks from MidwayUSA. Yep, gonna have to go one at a time and each stage seperately but it isnt the worst thing when just starting. Plus, you add dies for a second caliber and your savings are increased or cost spread over two calibers. If you shoot enough, reloading makes sense quickly even with start up cost of 500 bucks. I started with a dillon 550 for 9mm and 40. Spent 750 or so to get started. I got my 40 cost down to 25 cents, cheaper with brass I pick up. Retail was about 35 cents. I shot 7500 rounds of 40, which by my math saved 750. Not to mention that my ammo was more consistant and was loaded to meet my specific need(uspsa major).
