I'd like my AR-15 to have a little more THUMP

Check this out...

Big Horn Armory introduces AR rifle chambered in .500 Auto Max, a rimless version of the .500 S&W Magnum.





I'm not sure the world needs another cartridge, let alone another .50 behemoth; there's already the .458 SOCOM, the .450 Bushmaster, the .50 Beowulf, etc. out there that give .45-70+ punch in an AR

While I'm thinking about new cartridges, I want one based on the .500 S&W Magnum but necked down to .357 caliber. Something to launch 110-160 grain projectiles at plaid velocities. Call it the .357 Hyper Magnum or somesuch.

not a bad price for a proprietary ar-10, id want a little heavier of a platform for the round, though, the beowulf kicks like a shotgun and this is more powerful.

If I want a sore shoulder I'll just shoot my Mosin.

I shoot .500 S&W Magnum (S&W X-frame revolver), usually the Hornady 3oo grain FTX loads. Muzzle energy is around 90% that of a 12 gauge slug. From a handgun.

I just looked it up; the .50 Beowulf is no slouch, either. I wrongly thought it was just a little bit more than a .50 AE, but, no, it's pretty close to on par with the .500 S&W Magnum, with some loads being up to 2900 ft-lbs.

Actually, having looked up the .50 Beowulf specs, I see even less need for the .500 Auto Max.

Its obviously more of an "I can do this so i will" kind of thing. The beowulf was designed as a checkpoint gun. Coincidentally the round will mangle a feral hog. Not the greatest range though.

The need is always the same: MOAR DAKKA!!!!

You can never have enough dakka.

Banned in Jersey before it was even made!

I dunno. If I wanted something AR sized but with a bigger thump, I'd probably get an M1A Scout or SOCOM.

They have em in 6.5 creedmore now.

Sounds exotic, but I like 7.62N just fine. The bulk prices have come down a lot. I'm thinking about stocking up a little before we get much closer to the midterms.

It's a good time to do so, I've been stocking up a bit myself. My birthday present to myself this year was a 5.56 upper for my AR (so i could shoot it more than a couple of times a year) so i have a few cases of that laying around as well.

The 6.5 Creedmoor's raison d'etre is long-rang accuracy owing to its superb ballistic coefficient, which not only gives it a nearly identical trajectory to the venerable powerhouse .300 Win. Mag., but allows it to actually deliver more energy at longer distances, all with substantially less recoil.

I'm not sure why one would want this cartridge in an M1A. Don't get me wrong; the M1As are great guns--I have a SOCOM 16 that I quite love--but they aren't really all that accurate, not accurate enough to make the most of this terrific new round. Springfield's top model--the Super Match (.308/7.62mm)--costs around $3K but barely delivers 1 MOA accuracy; and Springfield doesn't even sell the 6.5 in that configuration, only in its lower-level "Loaded" series.

So many guns today, particularly the bolt action chassis guns, are delivering sub-0.5 MOA for a lot less money. Tikka makes a 6.5 Creedmoor (The Tac T3X) that will shoot better than 0.5 MOA all day long. The Ruger Precision rifle is another gun that almost certainly outperform the M1A at longer ranges. Spend a few extra dollars and the Desert Tech is another one that will reliably do sub-0.5 MOA groups.

I've been thinking I might want to get into long range shooting, and, if I do, the 6.5 Creedmoor will be near the top of the list in caliber choices...

its a good round to start out with, though the rounds come in a little light at 140gr, which might cause some problems once you get past a certain distance.

Lighter rounds are more susceptible to wind drift. If it's a concern, bring a .338 Lapua Magnum.

My Krag shoots .5 moa with hand loads. I wish like hell I could put a scope on it.

Hmmm?

I'm irritated that the .30-40 (like the .30-30) is named liked a black powder cartridge...but isn't.

That must be some sort of scout mount. The Krag ejects from the top of the receiver, so there's no way I can think of to mount a proper scope.

Probably military inertia. It was the first smokeless powder cartridge the US Army ever adopted.

I don't get it. Is it off-set or something?

I don't quite know. It looks like there's an angled surface that may kick the ejected cartridges to the side. (The empties eject upward, hit the slanted surface, and are bounced out to the side?)

In any event, it is a Krag with a scope, so it should be possible.

It looks like it may be one of these, which is an offset mount.

Installation:

I think it is off-set.

Ah, yes, I think you're right.

I just got a 420 round can of Lake City M855 from Ammoman for $180.

Nice, I have 2 in my armory, so I'm good for the year. The upper I picked up was a $250, fully completed one, so I'm time biding and parts building a second one.

So a couple of years ago I picked up a "blemished" Palmetto State Armory complete upper (and lower, though they were separate purchases) for a song.

A few months ago, I finally found the "blemish". The inside of the bolt carrier has excessive parkerization/phosphate in a place that should be in the white.

This is a problem for me.

So I picked up a nickel/boron BCG from Midway when they were having a sale a few weeks ago.





It made the bargain basement price of the upper/lower combo go up by a little more than $100, but that...spot...bothered me.

Only you...
