Wolf Ammo 40 S&W hates my HK USP

CA Blue

I recently bought a HK USP 40 so I am a bit short on funds. For target practice, I bought the cheapest new factory ammo I can find-Wolf. It now appears the 40 cal round jams in my USP 40 every 15 rounds with the spent case tightly stuck in the barrel. So naturally I tried other brands like Federal and Winchester after this, not a single jam with those ammo. Because it's not feasible for me to reload, and I shoot a lot, can anyone recommend a pistol chambered for 9mm or 40 S&W that can reliably shoot Wolf ammo? Thanks in advance.

Okay... this is a joke right? You're matching the gun to the cheap ammo you want to use? Hey, why not a Jennings 9mm? Perhaps you overlooked one little thing.... you won't be shooting cheap ammo if your life depends on it.Step up the ammo if anything... don't rid yourself of the wonderful HK. You'll find better deals on ammo, but there are few guns as nice.christian

Case stuck "In" the barrel? Wow! Your gun must not like that ammo at all. Here is the way I see it. You have one of the best guns on the planet in my opinion. It should shoot any factory ammo you put in it. I don't care how cheap the ammo is. I have never used wolf ammo in my .40 Ruger but I have never had any kind of ammo jam in my Ruger and I have shot several "bottom of the line" ammo's in it. Back to my main point. Your gun will shoot circles around my Ruger and your gun is better made. So that one has me stumped. A quality, high end gun like that not shooting factory ammo blows my mind. Also think about re-loading. The difference will amaze you and the price is right too. I am going to follow this post and see if anyone else is having the same problem. Good luck with your gun. Oh ya........I almost forgot. I had a S&W .40(sellouts!) that jammed every now and then for the first 100 rounds or so, then it never jammed again. So keep that in mind if the gun is brand spanking new.

You are probably having the same problem me and some friends of mine have had with wolf ammo. The cases are steel and lacquer coated, the coating is melting once your gun gets warmed up, that is probably 1/2 of your jamming problem. In addition the tolerences on the cases are not always what they should be, so that with the melting lacquer is probably why your cases stick in the barrel. We found this out by using Wolf ammo in full auto weapons, one mag and every other round would jam or screw up in some manner. I think that you find ammo like American Eagle, Samson, S&B, PMC, and some of the South Africain stuff, is still cheap enough to shoot and will function for target practice. I have 3 H&K's and even I can't get them to jam.

I have 4 - .40 SW semiautos & of all my HK USP is my favorite; the only time the HK misfeeds or misejects is if I use a reload that's too lite to cycle well. I've NEVER used Wolf ammo but it sounds like the lacquer coat is your problem.I'd suggest you locate a supplier of the PMC ammo (yellow box) or use Winchester's white box stuff if you can get it in case quantities. Shouldn't cost you more than $.20 a round.

The Russians seem to do a good job with ammo for the calibers they use, but seem to loose it when it comes to calibers they themselves don't use. HK's are a high quality high tolerance weapon. Their specs are very good. Wolf ammo specs (especially in that caliber) are not up to standard. I've talked to a number of people who have tried to use Wolf or other Russian ammo in their guns. AK's, SKS's, Makarov's no problem. AR 15's, Mini 14's, Walther's, HK's...problem. Don't switch guns so you can use questionable ammo. Stick with the HK and pay all of a dollar or two more for better ammo. The lack of additional headaches has got to be worth the cost. I found that out over a decade ago trying to use cheap .22 LR ammo. Sometimes it just isn't worth the savings of a penny here or there. You're there to shoot first, and save money second. If the whole point was to not spend money, you wouldn't be shooting to begin with. You'd just be sitting at home reading a book by candle light.As for PMC ammo, its not in a yellow box, that's UMC, from Remington.

Thanks for all the valuable advice.

If you don't handload, get Blazer ammo. I do handload but from time to time I buy Blazer ammo from Natchez Shooter's Supply when it is on sale. I also like Winchester's "white box" ammo and Federal's American Eagle ammo.

Case stuck in chamber? hmmm.......I've had several USP's in the past deacde. My first one was a 9mmV1 which I managed to put about 10000 rds of commercial reloads through it in a span of a year and a half. Not a single jam whatsoever. The second is a 40c and currently have about 1200rds through it...same thing, no jam.Considering the quality of wolf ammo these guys are talking about, I'll buy some tommorrow and let you know about the results. Hopefully, it is the ammo.-Smooth

tajjn raises a good point. Go to www.olyarms.com and read their ammo warning. It specifically relates to lacquer-coated ammo. Wolf ammo is also steel-cased which can cause problems for extractors but I would never guess that to be the case for an H&K. DON"T GET RID OF THE GUN! Every gun has it's own taste for the ammo it likes to eat. Test various brands of plinking ammo and find out what it likes. Then test different types of self defense ammo and find out what it likes. Then stick with what works for your gun. There is no perfect gun but H&K comes damn close.
