Mek what do you think about

[dsdmmat]

A 224 BOZ? If I could get my hands on one I would have it.

For those of you who do not know what a .224 BOZ is: 10mm case necked down to accept a .224 projectile. It is only in the hands of government forces overseas. They would not even sell the dies to load the thing.

I'd rather have a .357 SIG. Oh wait, I do.

hi,
I know we had our differences in the past so I am honored that you ask me.
I am going to assume the main goal is to shoot this from the typical pistol.
For carbine (alternative carbine made pistol) you have amazing choices from 30 carbine (223,6mm), tokarev (30,25), fireball, etc..
When looking at wildcats is easy to get carried away so think in terms of the platform you want to use and the maximum output that means
efficient powder burns and ballistics.
Also something that drives this are the bullets to be plentiful and well priced, that is why 223, 30 cal and 9mm/357 drive many to see wildcats
that can shoot those. Same thing with the cases, starting with cases that are plentiful and not too expensive ideally easy to find once fired
to use as donors.
In terms of the 10mm case, it is an awesome case but I think in 22 caliber will be hard to optimize in pistol barrels. If you like to do something
with the 10mm case take a look at both 30 caliber and specially 357 that is all ready to go. It is the 9x25 dillon and this will give the most
out of the 10mm case and pistol even carbine with affordable 115-125gr bullets. For the 30 you could get a bit more exotic but then
the Tokarev is so easy and it does so well that why bother right? There is also a 308 caliber tokarev that is basically the same but to use
308 bore barrels and bullets. Personally I would go for the 35 caliber and dillon.
If you still want a 22 then take a look at the 22 TCM that is also ready to go. No need to go to a 10mm case here IMO.
Armscor has the dies, pistols, barrels and even a cool bolt action that has been the baseline for 9mm luger super-fun bolt action builds.

makes sense?

It does makes sense but, if I was to do anything with a .224 BOZ it would most likely be in a 10 inch single shot pistol. Since we cannot have a sub-machine gun. I found the 224 BOZ story in the 90s and followed it for a while. It was very impressive for a 5 inch pistol. From what I recall the cartridge used to batter the crap out of the breech faces of the 1911 and the Glock they chambered it in. The battering was so bad the makers had a 1911 slide made with a replaceable breech face. The ballistics were very impressive though. Penetrate both sides of a Kevlar helmet at 100 yards. It would be an impressive cartridge in an MP5 type gun.

If I could have got my hands on one back then I would have. As far as the 9x25 Dillon goes I had the pleasure of being behind Robbie Latham (I was next shooter in line) shooting IPSC in Pheonix one year, it was impressive to say the least.

I here they do the job quite well. Many men and demons have been stopped cold dead in there tracks from a vital hit from them.

It's a unique round and would be tough to acquire all the necessary stuff to get shooting but I get it. Nothing like having an uncommon round to be able to shoot. I love shooting the 7.62x25 (tokarev). So much so that I not only got a pistol but the sub machine gun "pistol" (pps43) and sbr'd it. If you really really want to shoot this round it would seem you would have to have everything including the dies custom made.

I see..

IMO If you are going for a break open or bolt action pistol then check out the 221 fireball. For a 10-12" pistol this has to be the most efficient and easier and you can even buy ammo if you want. If you feel more exotic the 6mm version or even the 5.56x30 Minsas but I don't see any advantage over the fireball. Of all the PDW versions I would say the 6mm gives a tad more from a 10" barrel but with the fireball widely available why bother right? a lot easier to reload too.
They all do what the 224 BOZ does and much more. For a straight pistol the 22TCM is hard to beat, can be made for a number of brass sources including 223 and it will do the same as the 224 BOZ.

Back in the 80's and 90's we had a fever with 22 small variants but in the end there is nothing radically new to be invented. That is why I proposed the 221. Simple is good.

I thought the problem with these necked down 10mm cases was the extreme muzzle blast such loads generated. Wasn't the 9x25 dillons downfall in IPSC due to shooters having issues with hearing loss and tendonitis? Wouldn't a .22 vertsiin worsen these issues? Or is that an overblown thing?

 

[meketrefe]

Anything above the 357 sig for a 4 or 5" barrel is totally unnecessary. I think for the objective of 10-12" above it makes more sense.

Another issue with light bottleneck high pressure high velocity cartridges in auto loading pistols is that at some point one needs a gas operated system (heavier pistol) to provide safe pressures before opening. Blow back could be dangerous.

By the way, the 6mm version I was refering two is the 6mm-221 or 6mm whisper. This one adopted by the knights armament for their
PDW. All the same principal. Smaller than the 5.56 and ideal performance in 10" barrels.
But even the 223 itself can be loaded to be a lot more efficient in a 10-12" barrel. It does better than the 222R just because the 5.56
brass can take 62k psi without problems. Same thing with the 221 fireball that has stronger brass than the 222R.
Although 222R lapua brass is also very strong. Of course the 222 and 223 are longer rounds than the fireball and whisper.

Yeah back then it was pretty exciting to read about a pistol that could penetrate both sides of a Kevlar helmet at 100 yards. Not practical by any means though. Something got me thinking about the BOZ today, that is why I posted the question.

I am going forward with my 5.7x28 ( 10 and 16 inch barrels) T/C encore also thought about getting a 16 inch 38 super barrel made for it. I have tons of 38 super brass, bullets and load data. A 35 Remington 20 inch barrel will be made as well.

The 5.7 would make an awesome little survival round that one can reload. I mean, one can carry a lot of them re-loadable tiny bitches.
If time and dedication was not a problem I would love to have one of those savages in 5.7 now discontinued but that one can find
in the gunbroker and alike. But otherwise the TCM alternative seems like it could be a lot of fun too. People are using those from
Rock Island to build little 9mm bolt action carbines too. This would have been very handy when people could not find any 22LR and
one could reload 9mm for a bit over the cost of the 22LR CCIs. Same with the 5.7. It takes little powder and affordable varmint bullet value packs.
