This is a followup post to my topic called "Misfire". Last monday, I had about 10 rounds misfire on me while at the range. I was shooting my Ruger P95 9mm. The firing pin touched and scratched the primers but they didn't go off. I cleaned my gun real good, and went back out today and shot with Winchester & Remington Ammo. I shot 150 rounds and not one malfunction. So I'm beliving its the ammo and not the gun. My advice is stay away from Olympic Ammo, its cheap greek ammo from Sportsmansguide. |
My experience with the Olympic ammo was with their .223. It wouldn't cycle a couple of friends' ARs with 20" barrels, but ran flawlessly in my M4 with a 16" barrel and carbine-length gas tube. We theorized it has something to do with longer dwell time in the gas system in my M4 allowed it to build enough pressure to cycle my rifle. At any rate, I got a bunch of free ammo to shoot...

Problem on the Oly 9MM is the rim of the case is thinner/smaller diameter. On some pistols with less then stellar case retention, this allows the case to slip deeper into the chamber and not be retained tight against the breach face. This means that firing pins with short protrusion, coupled by Long chamber depths tend to not want to set/ignite the primer. Another problems do to the retention is that the extractor tend to not grip the rim fully, and can loose the case on the way back. Bottom line with the slide only in hand, is to inset a case onto the breach of the slide, and see what kind of gap you have from the forward surface of the rim, to the claw of the ejector. If it's too great, then it's time to either have a new extractor fitted, or find ammo that has a thicker rim to compensate for the less that idea claw to breach gap. |
