I just purchased 1,200 rounds of Hirtenberger 124 grain FMJ (1991 production). The man that sold it to me told me that this load was a little "warm" for handguns (confirmed by a label on the top of the ammo can).

My questions... Do any of you have experience with this load? Should I avoid using it in my 9mm chambered handguns (modern SIGs, H&Ks, Brownings) and only use it in my rifles? Lastly, what kind of velocity can I expect from this load from a 16" barrel?

Is this L7A1? [url]http://www.ar15.com/forums/topic.html?b=1&f=5&t=183634&w=searchPop[/url] I have fired this ammo; be careful with it.

Thanks for the link.... Yes, it's the L7A1 ammo, 1991 production. There's a circled "+" on the case heads. I purchased it specifically for use in a Sterling Mark 6 (semi-auto version of the SMG). My Sterling functions best with "hotter" ammo. I may also try it in my Uzi and H&K 94 for grins. I guess I'd better pay attention to the warning label on the can and avoid using it in my handguns.

The problem was some venders selling this ammo as +P+, which it is not; more like ++P++.

A buddy of mine who knows a whole lot more about these things than I do told me to use it only in "blow back" type carbines such as my Sterling or and Uzi carbine. He advises against using it in any firearm with a locking bolt action (i.e., the H&K 94).

Your buddy has some good advice. All will become clear when you pull the trigger.

The BAT boys even have advice about the L7A1 Department of the Treasury ATF Office of Public Information For Immediate Release FY-97-6 Contact: Vickie Saunders Date: November 7, 1996 HAZARDOUS AMMUNITION Washington--The Bureau of Alcohol, Tobacco and Firearms (ATF) has been advised by Hirtenberger AG, Hirtenberg, Austria, that certain 9Xl9 mm caliber ammunition produced by Hirtenberger is unsafe for use in any handgun.

Thanks much for the info. I think I'll reserve this ammo for my Sterling. From what I've read, it was designed for that application anyway. Once again... you guys have helped me stay out of trouble. I appreciate it.
