OFFS, more old obsolete calibers in dusty boxes on the top shelf in my future.

Likely defeats Level II armor.
Meets a need. I just built one with a 9" barrel that accepts 30 round AR mags. I call it the 300 Blackout Lite when loaded to below 2000 FPS.... |

We needed something to bridge the gap between .25ACP and .32ACP?

Holy fuck, this might actually be something. I already want a 6-shot hammerless J-frame clip gun with a shortened cylinder. |

Aha, 115 at 1160, not 1250
Still high cap for gun size could be interesting. |

.05" smaller diameter case than 9mm, so that's +1 in a mag, right?
|
|
Fuck yes. Now build a modern Pedersen Device to run it through .30 bolt guns.
Because Fuckit |

YEP! other than extending the cartridge case length about .010" or so, it actually is a magnum styled version of the 7.65 french Longue, as the OAL is within .08" of the original round... They elongated the case for powder capacity and shortened the bullet to achieve maximum velocity. They played with the dimensions, but any reasonable person would assume this could be fired in a French 1935s pistol with a properly reamed chamber... What's old is new again!

Ask for new 38 Super guns and HSTs in the same and we get 30 carbine short instead

Cool first post. Welcome to Arfcom. |

Wonder about Velocities
F it I'm going to buy all the ammo when it comes our before there's a demand . |
|
I just want a Springfield Mil-Spec Stainless, chambered in 9x23. Im not asking for much. They've already done parkerized .38 Supers.
|
|
"no tradeoffs"
Well. At 50kpsi, bullet setback is now going to be a hazard. |
|
Man I've thought about making a longer, stronger casehead .30" pistol cartridge for a while. You could exceed 9mm in capacity and get some nice ballistics with low recoil.
Like start with a .32 ACP, ditch the semi-rim, extend to about 1.300" COAL and make the casehead able to withstand 40k PSI. It's like they got in my head. I even figured 115s for supers and imagine how quiet some 160gr subs would be. |
|
I like weird calibers. But I want the option to shoot through both sides so I'll stick with the 10mm
|
|
Has my interest.... but a 1911 and a shitbox S&E EZ are not the guns I want it in.
|
|
Put that thing in a lcp max and give me a 15 round pocket pistol!

Quoted: OFFS, more old obsolete calibers in dusty boxes on the top shelf in my future. View Quote Why though? In a full size this would get you 20-21 rounds flush and we all know the actual performance would be on par with 9mm since there is miniscule difference in bullet diameter. Sounds like it could easily be a 9mm replacer going by all the metrics used in ballistics. |

Quoted: Dang. What a waste. .30 at 1200 is better than .35 at 1250? View Quote View All Quotes View All Quotes Quoted: Quoted: I wonder if this is some new wonder round being introduced at SHOT show and a few retailers jumped the gun. Found something saying the 100 grain ammo runs around 1200fps... so basically it's a smaller diameter 9mm... and for what? Dang. What a waste. .30 at 1200 is better than .35 at 1250? Well it fits the 9mm is better than .40 S&W which is better than .45acp because bullet technology bro types. They should jump on the extra capacity no downsides because bullet technology bandwagon just like every other smaller cartridge bandwagon. Will it happen who knows but it will be interesting to see what marketing can do. |

Quoted: Isn't the FN 5.7 a 20rd capacity? It's a big pistol though (light, but big for CCW). View Quote But diameter of the brass for the round is something like .311, .32 acp is bigger even. And the fn5.7 Is bigger than a glock 17 (grip length is .5 inches longer) and so where around 1.4 inches thick vs 1.1 got a glock 17. |

Hell you could make a standard 1911 hicap with the cartridge. Ejectors might be the difficult part. |

This could actually be a pretty cool development. With the smaller case diameter, gaining a few rounds capacity over 380 and possibly beating it ballistically could be a nice improvement.
I’ve always thought 380 was a stupid round, being the same diameter as 9mm and just a tad shorter, but a much weaker cartridge. It just never made much sense to me. This round could make up the difference. |

IN before all the youtube shills release videos about this at the same time.
