https://www.thehighroad.org/index.php?threads/kahr-auto-ordnance-m1-carbine.885422/ so now a update on ammo tests. After slowly gathering different ammo during this ammo shortage and high price in these days and age, did a trip not long ago and tested several brands. Best groups as far as size were S&B FMJ and Armscor FMJ ammo. Worst was Fiocchi ammo. As far as hitting center mass as sighted in at 100 yds, I know now that S&B soft point, PPU soft point and FMJ, and magtech are the best considerations Had a couple stove pipes, but function was about 95% reliable with all ammo. Armscor seemed to be the hottest loaded ammo.
