Wife and I went to the range yesterday. She picked up a few boxes of Wolf 9mm for me. Great price online. Well, I shot 250 rounds of the stuff thru my XD9. Not a happy camper. It was more like shooting a black powder pistol, that much smoke. I finished off the boxes she got for me (never look a gift horse in the mouth) and started in on a WWB wallyworld buy. My first ever FTE! On the first round of Win. Pulled the slide off, and the extractor looked like a half moon, that much gunk built up on it. I'm 99.999% sure it wasn't a build up of oil to attract anything, I clean it after every range trip. My only idea is the Wolf ammo. After a quick brushing, the XD performed flawlessly thru another 100 rounds (like I expected . No more Wolf for me! Has anyone else had any experience (good or bad) with Wolf(I'm not trying to slam this company, just a bad experience I don't want to repeat)
