A couple of weeks ago I was shooting my FNC and it was running like a Swiss watch while I emptied a couple of mags. These mags were already loaded when I arrived at the range.
I guess I must have 5-6 brands of mags stored in a SAW ammo can and I've never really bothered to check and see what brand mag I pulled out to reload because it's never been an issue.
I loaded a few more mags and returned to the firing line, but all of a sudden my FNC refused to feed. I had no idea why because this little gun is about as close to 100% as any gun I've owned. I didn't spend that much time trouble shooting the situation and started shooting .308.
I've since read about all of the D&H problems on this forum and you guessed it. I went back and examined the mag I was using when the problems started and it was a D&H that was mfg on 3-05.
Mystery solved and happy day.
