My HK P2000 HATES!!!! Wolf .40 cal ammo.
1 out of every 25~30 rounds splits down the side of the casing and gets stuck in my chamber. Won't extract what so ever.
I have to run a metal rod down the barrel and pound the casing loose.
And before anyone says maybe the batch of ammo was bad, I tried Wolf when I first got it, did this. I tried it again 6 months later, same crap.
Then last week I bought 2 boxes because it was on special for $7.99 and I thought I would give it another try now that the P2000 is good and worn in.
I got threw both boxes of 50, 100 rounds total without a any issues. I was so happy I went back and bought 10 more boxes. I got the range the other day and guess what happened within the first two magazines? Then 3 more times within the first 2 boxes. I said screw this and called it a day.
My GLOCK 23 feeds the Wolf flawlessly though so it's not that big of a deal but it annoys me.
I don't think it's an issue with the HK P2000 though because I've shot thousands of rounds of brass cased ammo without any issues.
