Folks useing some of the exotic ammo I have seen listed-how much did it cost you to run enought ammo thru the gun to confirm load reliability, like maybe 200 rds? Whatever the drawbacks of useing ball, like some do, I expect that the jam factor is lots less with good ammo.(I had seen misfires and problems with the Russian steel stuff). I used to load the so called "Air Force" bullets that were a FMJ with a coned nose and a flat tip. Think it was Hornady bullets. Supposedly had more target terminal shock than a round nose bullet, but was originally a 9MM bullet design?
