Russell - no one is born knowing all this stuff. We all had to learn somewhere! Full Metal Jacket, or FMJ, refers to the lead bullet being jacketed in copper. The copper jacket helps it to feed better in your semi-auto and reduces lead fouling in the barrel.Russell wrote:As far as the full metal jacket having nothing to do with the case, sorry if I sound like a dunce I'm still learning as this is my first handgun purchase everWhat does "full metal jacket" mean then?
The important thing to learn is that cheaper is not always better when it comes to ammo. You have an expensive firearm, feed it well.
