I ordered and received some 10 boxes of 9x21mm Fiocchi Pistol Shooting Dynamics Full Metal Jacket 123 Grain 1280 fps 50 Round Box that I intend to shoot in my 356 TSWs... As the add says FMJ I assume that is a copper jacket...
Well I have never seen these 2 things in the same bullet, it states on the box both "Copper Plated" and also "Full Metal Jacket"...
I always thought plated was like the .22 ammo lead with a copper plate, and full metal jacket a metal jacket (copper) with a lead core, you know like you make and swage rifle bullets to get match grade bullets...???
What do I not understand...???
Thanks and have a good one...XPman...
