Hi I received some literature the other day (which my wife threw out ) that was advertising a semi auto pistol that shoots a new caliber that is a 38 necked down to a 32. I believe corbon had something to do with it. Can any of you guys give me any info on this please thanks

Paste this into your browser-of-choice: http://talk.naaminis.com/room_178/780.cfm Apparently they're working out some last-minute details & the little critter's haven't been turned loose just yet. Anybody know where I can get one of them BMG.223 autoloaders, please? There's a candidate for governor here in Illinois who has a blind fear of 50 caliber weapons & they just might outlaw 'em.
In Feb.1987, I got between 185 and 200 ft lbs m.e. from a similar cartridge with a 40 grain bullet but out of a longer,3 1/2" barrel (ppks). Pressure was 30-35,000 psi cup (measured) which is plenty for a small blowback pistol. To get similar results from a 2 1/2" barrel, pressures have to be quite a bit higher.
Slide velocity was too high for the PPK slide weight, even with duplex springs, and the PPKS was damaged from the battering. The NAA has a lighter slide.
Even if the NAA has a locked breech, it has to take a hell of a pounding to produce the alleged numbers.
I'm not from Missouri but seein is believin.
