Quote:The .416 Hushpuppy, a new proprietary round being offered with a AR upper by AM-TAC Precision was announced at SHOT this year. The concept to the round is claimed to have a maximum point blank range to 200yds on a man sized target, and creates a wound channel larger than 12ga 00 buck or a slug due to the yawing characteristics of the bullet when it encounters a soft target. The round is designed to be shot suppressed, and AM-TAC is currently working with suppressor manufactures to have a suppressor made for the round.

While it is definitely a funny looking round with an even more interesting name, the initial numbers that are being put out there by AM-TAC look promising. The rounds ballistics are being compared to 12ga rounds in terms of the amount of energy dispersed and wound channel sectional data. The round is designed to be marketed to the LE and hunting community, and would make a great hog or predator round. The upper is made with all commonly found products, except the barrel which will be proprietary. The bolt carrier will be a standard AR BCG, the bolt will be a 7.62×39 bolt. While AM-TAC will be producing the bolts, in a pinch one could find a 7.62×39 bolt and put it in the rifle if needed. While the ammo will also be proprietary at first, AM-TAC will have a company that will OEM the brass for reloaders, while the bullets will be available off the shelf.

While I do not think this round will be the next .300BLK, I do believe that it will have a following if AM-TAC is able to get the word out, and keep prices at a believable level. As a predator hunter myself I would be eager to use the round in a hunting application to see how it handles. We will certainly have to see if the round stands up to the test of time, and the discerning shooters out there that will be shooting the round.

Looks like a solution looking for a problem IMHO...


416 hushpuppy - NugginFutz - 01-19-2014

Yep - but that type of marketing works all too often. Generate the perception of a problem, provide the solution, and cash in. Oh, wait - that's politics.


416 hushpuppy - longdayjake - 01-19-2014

Oh it already has a mountain of problems. The first is brass. The second is that there are very few bullets for it. The third is that it is made for subsonic work yet very few silencers exist for that bullet diameter. The fourth is that powder options are quite limited and finicky. It is cool looking though.


416 hushpuppy - GMinor - 01-19-2014

No thanks.

A slightly bigger Blackout.

I'll admit to being sucked-in with the clever Blackout marketing. Two years later and it's like buying a burger and wondering why it doesn't look like the photo above the counter..

For example, that stated 200M is more like 100M. No doubt in their testing if you point the gun to the sky the bullet will make 200M, but after 100M you'd better have a good scope and know exactly what range your target is. Heavy subsonic is rainbow trajectory, plus the Blackout is defined by over-penetration (sold as a marketing plus, until you start shooting game which trot off to die somewhere else). I can only imagine this heavier .416 will be even worse and like the Blackout users will be stuck with projectiles made for supersonic use. Hollow-points and soft points don't open up under 2,000fps.

You can get Blackout rds to yaw as it is. Just load a pointy match rd and they tumble on hitting flesh every time. It's interesting to listen to. No supersonic echo...It's less than 100M so it's a loud slap followed by a zinging sound as the bullet exits the other side. But don't expect the same killing power as a supersonic hunting round.

Hunting subsonic is a very poor proxy to supersonic and unless you are using a suppressor where you really need it (e.g. killing German sentries!) there is no other practical advantage. May as well use a suppressed .22 or 9mm...they are both quieter.


416 hushpuppy - bwaites - 01-19-2014

I've wondered about the advantages of the Blackout. I keep coming back to the fact that my 230 grain .45 round has a bigger meplat, travels at a little slower speed our of my 1911, and actually mushrooms on impact, making it even larger than .45. Shoot that same out of a 16 inch Beretta Storm and it supresses nicely, nearly matches a 220gr Blackout bullet in speed, and is accurate at 100 yards, and is still traveling plenty fast to make a bad guy think twice.

I think the Blackout is a cool idea, I just can't figure out where it would fit in my "useful" arsenal.

Now the Hushpuppy comes along, and ......

And no reason a .45 suppressor wouldn't work just fine on it, if you really wanted one!


416 hushpuppy - GMinor - 01-19-2014

Hornady tests their A-Maxes to ensure each lot will expand at 1000 fps upon entry.

I could not agree more.

Your .45 is a larger diameter than my Blackout, and with projectiles designed to work subsonic with decades of bullet manufacturer R&D behind them. The Blackout is a smaller diameter 30cal with supersonic match rds. For example, the Hornady has chosen their 208gr FMJ for their Blackout subsonic ammo. I have no doubt that on hitting flesh the .45 will work better.

At least the Blackout can shoot supersonic also, which is something this .416 'Hushpuppy' cannot do.

Love the sexy name though, 'Hushpuppy'...I already want one!

Take it from me, subsonic FMJ match rounds do not expand when they hit flesh. They tumble and bend but do not expand.

Even dedicated subsonic flesh bullets like the 220gr by Outlaw State goes in one side and out the other. You cannot tell the entry hole from the exit, and that's with the few animals that die in the vicinity and do not simply bolt off into the scrub. Subsonic Blackout uses only 3/5 of the SAAMI peak chamber pressure so don't expect bullets to do very much when they get there.


416 hushpuppy - GMinor - 01-19-2014

Where in my statement did I say ANYTHING about a FMJ?


416 hushpuppy - Klem - 01-19-2014

OK, my apologies, allow me to be absolutely precise.

I have hunted subsonic Blackout with the following projectiles;
Hornady 208gr Amax
Hornady 220gr RN
Berger 210gr Hybrid Match/Hunting
Sierra 220gr SMK
Sierra 225gr SMK
Sierra 220gr RN Pro Hunter
Outlaw State 220gr

None of the animals that I have inspected have had the projectile expand. Admittedly I have not cut open all of them and half simply run off wounded. As I said, subsonic hunting is not the same as supersonic. It's all about shot placement at close range. I have settled on the Sierra 220SMK in my system which is a 1:8twist, 16" carbine gas. They cycle fine and tumble on impact.

So Mr Minor, what subsonic projectiles have you hunted with in your Blackout? You have a strong opinion against someone who has so lets hear it? Any photo's?

(Please note, none of my post is in all-upper-case, but I can 'shout' at you if you want).

Haven't tried the LeHigh projies, only because they will not cycle in my system.

My systems subsonic window of available projectiles is 210-225gr. LeHigh produces two designs of subsonic 30cal projies and they are both too light for my gun. They make the Controlled Fracturing in two 30cal weights; 170gr and 174gr. The other one is their ME (maximum expansion), however this is also too light at 200gr.

The Blackout is inherently under-gassed with the large diameter barrel dropping the chamber pressure quicker than smaller calibres (.223 and 6.5). In its early days barrel manufacturers were pretty much making all barrels with carbine-length gas ports (including the one I have). By the time the bullet passes the 7" mark there's not a lot of pressure left to cycle the action. This is especially evident when using subsonics which are loaded to only 3/5 the SAAMI peak chamber pressure. If I load anything under 210gr it will either be too fast/supersonic and cycle, or be subsonic but with not enough pressure to cycle. At the top end anything more than 225gr and you risk not having enough case capacity with the length of pointy projies (the COAL is fixed at 57mm due to the internal length of an AR mag), or being too heavy for the 1:8twist and so being unstable. Barrel manufacturers are now selling Blackouts with pistol-length gas ports and slightly faster twists 1:7.

Getting back to LeHigh. Even if I could load their rounds I doubt they will be any different to a .45cal handgun hollow-point. Probably the wider 45cal diameter will slow quicker in flesh than the 30cal Blackout.

Both LeHigh and Outlaw State subsonic bullets are expensive at about $2 each.

My thoughts...I like the pointy projies with plenty of mass at the back of the bullet. On hitting flesh when subsonic they want to quickly reverse and that causes the tumble.

I forgot on the previous post to include the 200gr Lapua subsonic. Again, this does not cycle in my gun but in pistol-length gas systems you could get it to. Regardless it does not do anything except laser-beam through flesh.

I like those Twang-n-bang clips. I find he is very fair and reasonable with his reviews.


416 hushpuppy - KentuckyBuddha - 01-19-2014

They are certainly expensive and he mentions that they would not be a great idea for home-defense for that reason. It appears they just have a long OAL yhea? It definitely proves the concept that it is possible though. Perhaps pill with a polymer tip and perhaps with the grooves in the inside of the tip would give the same soft tissue effects without sacrificing aerodynamics or feeding. If "holding together" and over-penetration is what you want, the Lehigh seems to do that in spades too.

Surely if one company can make/have made pills like this one or many of us could do the same with improvements.


416 hushpuppy - Klem - 01-19-2014

Agreed.

Unless you are hunting bigger game than humans I reckon all current 30cal offerings are prone to over-penetration. I would however like to see a compressed lead powder bullet similar to the CorBon Safety Slug. Corbon uses small lead shot with a polymer expander ball at the front. I'm thinking the same design but use lead powder instead of shot for a heavier round, and so make the weight threshold needed to cycle an AR.

I helped a friend with his Blackout, and we had these same issues. He had the gas port opened, and then ran an adjustable gas block, so that he could shoot both super and sub-sonic. It seems like most rifles will do one or the other well, but not both, unless you have an adjustable gas block.

It seems like finding a good balance to run light supersonic bullets and heavy subs is very difficult. No surprise when you are looking at bullet weights where the subs approach being twice the weight of the supers, I guess!


416 hushpuppy - GMinor - 01-19-2014

I dont hunt sub sonic. Loading sub-sonic is for the birds anyways.

AND I live in CA so there is really no point.

Anyhow, here is a pic of what a 208 A-Max does on impact with hard and soft tissue, and a combination of both (if I can find the last pic)

Hard target (3 treated 2x4's)

Soft target (12' of SOAKED paper, same method Hornady uses to test they projectiles)

It was my understanding that Hornady does not recomend the A-Max as a hunting bullet but only as a target bullet, so I am surprised they would even test for expansion.

"Loading subsonic is for the birds anyway?" I admire your confidence, if not your opinions.

I have done some 'wet-pack' (wet newspaper) testing of the Hornady and Sierra 220 gr RN round noses (only) with all other results from hunting. Sample sizes are few with about a couple of animals per bullet type, so hopefully that puts it in perspective.

Your pictures are not what happens in flesh. I sometimes use 'wetpack' testing but have found it a poor proxy for live animals, the aim being to kill them as quickly and humanely as possible. With wetpacks it depends what type of paper and how compressed the pages are to each other. For example telephone books act like solid wood, even after being soaked in water for a week. What they are good for is relative penetration testing and recovering the bullet easily. Regardless, if the bullet exits 12" of wetpack then that suggests over-penetration in flesh.

Your top photo is pretty much what I have seen in all types of subsonic rounds on flesh. Slight bending of the bullet in flesh but still pretty much in one piece. No temporary wound cavity and no kinetic shock like a supersonic impact. The animals are slow to die compared with supersonic. Every one has required a follow-up shot at close range to dispatch them.

You are weighing manufacturer information (biased?) having used wet paper as a clumsy proxy for flesh against someone with no agenda who has actually used them on flesh. If the results differ and you are wondering who to believe I'll leave that up to you. If it is important for you to hold dearly the information that first comes to you then by all means, believe what you want. From my perspective I am happy to share my experience with someone who has none.

Where do they put the powder? It looks like its all bullet 😜
