4.6 X 30 mm Ammo??

MidwayUSA had stockage of it before the "troubles". I suspect the Fiocchi load in question is NOT steel core, but a ballistically similar lead core. Your LGS may have ordered thinking it was "something", and not realizing the number of so chambered guns in the US is pretty small. I am not sure why Midway even had it- maybe hoping a SOCOM guy with a unrestricted .gov credit card might need an urgent order?

I'm sure it wouldn't be hard to chamber an AR for the round.

In fact, I'd be surprised if somebody hasn't already.

If I had spare cash id probably buy some to hold on to. Looking on Gunbroker theres 2 listings I found. One was for Fiocchi going for over a $1 round. Another that's starting at $175 for a box of 50

It’s used to feed a trick Teutonic burp gun. Good stuff.

CMMG already makes one in that caliber.

There have been a few videos on that new CMMG offering in the past week, I honestly haven't seen any ammo for it in person, but had heard Fiocchi was importing it before the CMMG was available for some reason.

Not sure I get the "why" without AP offerings and full auto capability, but it should be sporty trying to reload those wee cases with .184" bullets that no other chambering uses.

4.6mm is of no more use to ME than 5.7mm, but it's still interesting.

150 yard round max, but said to be laser like up to that range.

Meh...Ill pass. Its just a little hotter pistol round IMO...with a higher price tag.

Reminds me of a necked down M1 Carbine round a la 5.7 Johnson Spitfire.

I want Lee dies for this caliber.

It might seem like a novelty cartridge now, but who knows where it'll go. It may catch on or may not. People used to think .300 Blackout would die out, but then more and more manufacturers started making guns for it and look where we are now.

We'll probably never get the MP7, but HK could at least give the UCP prototype a little more refining and put that on the market. I'd wager that that alone would make the 4.6 really take off. CMMG is doing their part, but more gun makers may have to step up to the plate.

To be fair on the why, I guess 5.7x28 and 4.6x30 were both NATO standardized this past year (STANAG 4509 and STANAG 4820). So while 5.7 is clearly ahead commercially, maybe they are on somewhat of a similar footing in the grand scheme of things. So if we are playing with 5.7, I guess the question is why not 4.6 too?

IF Ruger came out with a version of their 57 pistol for the 4.6 (or similar from another manufacturer), and IF components and were available and reasonably priced, and IF there weren't any special tricks or coatings involved in reloading 4.6 like there seems to be in reloading 5.7, it might be a fun little cartridge to try. What I really want is an MP-7, but I'd certainly take a copy if it were available (looking at you again Ruger...)

As with the 5.7x28mm round, I think this would be interesting in a rifle the weight and size of a 'serious' .22 long rifle specimen. Bullets would have to available, of course. This sort of thing could be the logical successor to the .22 Hornet round.

I just checked, 5.7mm is .224 inches. 4.6mm is .18 inches. It makes one think the 4.6mm is essentially a BB gun caliber using a Minié ball type projectile instead of a round ball.
And I still haven't figured out a reason for 'civilian' (non-sniper) use for a .300 Blackout.

A lot of hog hunters would disagree about the .300, Archie.

I was wondering if the 4.6mm was created to utilize bits and pieces left over from the G11 projects.

It's a tiny bullet but that sort of seems like a trend.

The .300BLK makes a good short range deer pistol in an AR platform. Easy to carry & easy to move through thick woods.
Light enough to carry for a long way on public ground where they don't allow wheeled vehicles.

The 4.6x30 looks to be made for a penetrator round being it has a copper coated steel 26gr or 31gr round.
As far as a hunting round I would use the .17 HMR it's just about as fast & much more able to find some ammo.

That presumes one accepts an AR platform. I have had no need (and a distain) for that platform since 1974. I know, not everyone agrees with me. Wonder of wonders.

Doesn't sound so impressive, now does it?

Not to my taste either. I've never liked .17 caliber except in BB guns.

To have someone or some group disagree with me is merely life. I do not find any particular reason to use this round at all. Others do? Then let them be happy.
I'm really pretty jaded about pumpkin pie, too. Have been for years.

It just seems pretty underpowered to go spending well over $1500+ for a semi-auto pistol carbine. If I could get the full auto version, that makes a lot more sense. For semi-auto, I might as well go for a 5.56 pistol (or something similar) that has a little more power per round and still pretty good capacity.

Fixed it for you.

The way you wrote that sentence,

implies that you cannot conceive of other uses for the .300 Blackout other than it's original designed use, which was sentry removal/CQB. I know you're smarter than that. Many of the cartridges we all know, love, and use started out with a different purpose, often military. But this does not limit their use to that original intended purpose. One can use 7mm IMSHA (loaded with SP's) for hunting, or self-defense, if the only gun you owned was an XP-100 in that caliber. Is it optimum? No, particularly for self-defense, but that has less to do with the caliber than the capacity.
I'd be willing to bet that more hogs have fallen to the .300BO than sentries or enemy combatants. Toss in the deer taken with it, and I'd say as a hunting cartridge, it's here to stay. Maybe not the popularity equal of .30-30, but certainly a capable round for many purposes other than the original intended one.
Don't like the .300 Blackout? There's nothing wrong with that. Don't get one. I don't have one myself, but not because I haven't figured out why it is being used for purposes other than the intended one.

I must admit to the correction being arguably correct. It may be a personal matter. Probably more hogs than sentries and so on. However, I would be willing to bet most hunters have adequate arms already in possession that would adequately serve in that capacity. I see no need to supplement or replace for that purpose.
Unless one needs to be first on one's block.
