Fiocchi ammo question

[Rags]

A friend bought 10 boxes of Fiocchi in .40 S&W. The first two boxes, which were white (I hope I'm remembering this accurately) functioned his new gun just fine, but the next several, which were brown, caused a malfunction on about every other round.

Has anybody ever heard of this kind of problem with Fiocchi?

I shot up a couple of cases of .45 acp from them about a year ago with no problems to speak of.

I did have a problem with some Fiocchi .45 a while back in a very particular, high end 1911,
but I solved the problem and we are divorced now.....................

I've shot MANY different brands of .40 in my M&P. Everything functioned flawlessly except for Fiocchi. One in three rounds jammed. That box of ammo was completely incompatible with my gun.

Any idea what may have been different?

I have no data. My guess is that the Fiocchi .40 overall length is wrong for the M&P (most likely too short).

This isn't exactly related but Fiocchi cases were one of the worst with a reloading issue I was having.Firing these in an unsupported barrel such as a Glock 26 the case would expand larger at the base than most other brands of ammo, my RCBS dies were not resizing these cases all the way to the base and therefore I was having problems with these rounds going all the way into the breach on my Springfield EMP. This leads me to believe these cases are either a softer brass or thinner cases. Whether this has any bearing on your Issues I not sure.

What firearm was it?

I've got some south american .45ACP that shoots fine in any 1911, in my Ruger P90 about one round per magazine fails to fire (it always goes off on the second hit), and a friend's Glock won't fire them at all. It's good ammo but with very hard military primers.

What sort of malfunction does he have?

I shoot Fiocchi in several odd calibers and I haven't had any problems in my mostly military firearms but that has only been a couple of hundred rounds in total; the stuff is expensive!

[Rags]

Thanks for all the info, guys.
The gun is a S&W M&P .40, and he says he has no problems with any other ammo.

What type of failures, light primer strikes, jams, failure to feed?

I think it was failure to feed and jams, but I'll ask him.
