I picked up a few boxes of the Hungarian made MFS brand 9MM 115gr FMJ ammo from Cabala's some time ago. ( Black and white box with a blue stripe )It was inexpensive ($14.00 / 50). I finally put it through my G19 last night, at least what would fire, and holy crap! This has got to be the worst ammo I have ever used. There were times when I swore I was shooting a black powder handgun with all of the smoke and debris coming out of the barrel. I actually saw sparks at times. Talk about distracting. I had numerous failure to fire situations too. The primer was dented but nothing happened. Once I put them back in the mag and gave them another shot they fired. My gun was a total mess as well. I had more black soot in the frame after this practice round than what I would normally have after shooting ten boxes of Winchester ammo. Maybe I just got a bad batch of ammo but I will not be buying that brand again. As far as accuracy goes, It shot reasonably well at 50 feet. Has anyone else experienced this with this brand?
