New Winchester 9mm Army round

[ST911]

I am highly skeptical that anyone could get that velocity with M1152 from a standard pistol length barrel (even though the article says it was from a 4.7 inch barrel).

I'm not. That's neither difficult nor unprecedented.

I wonder if we will see an epidemic of broken pistols in a few years like we do with the M9. Every regional and national event I attend has M9s break their locking blocks. I know a guy who has broken 3, though that is probably a freak string of events for the individual.

Not unreasonable velocities

"In our tests in 1985, XM882 propelled a 124-gr. round-nose FMJ out of the 5" barrel of an M9 at an average of 1273 f.p.s., delivering 446 ft.-lbs. of energy at 15 ft. Using an Oehler Model 43 and firing the new ammunition out of a 4.7"-barreled P320-M17, M1152 with the 115-gr. bullet was at 1326 f.p.s. and 449 ft.-lbs. of energy, while the M1153 clocked 962 f.p.s. with 302 ft.-lbs., both at 15 ft."

So a 124 FMJ at 1273, a 115 FMJ at 1326 or a 147 HP at 962.

So I'm confused.

I thought they had a contract with sig for ammo. Is winchester making it too?

[mack7.62]

I am not sure Sig has the capacity to fulfill a military contract, likely they are subbing at least some out to Winchester.

Paragraphs 2-4 of the article answer this.

I wonder why the Army did not stick with the 147gr hardball they had been using, the stuff that was basically loaded to +P. I bought a slew of it a year or so ago from Brownells, in original Army GI sealed cans, etc.

[mack7.62]

You know just dawned on me that by going with a 115 grain they are throwing all pretense of sticking to the NATO standard out the window. Not that that's necessarily a bad thing.

Maybe they have a range in some weird combination of the highest elevation with the least dense air but very hot like a mountain on the equator or something.
