So I have been into shooting for a few years now. Since myself and friends tend to shoot a lot, almost weekly in summer sometimes, we found that aluminum case ammunition was most cost effective in our area sine none of us were interested in going through hassle of reloading ammo. We have run thousands and thousands of round of aluminum case ammo through all types of semi autos and never had any malfunctions or issues. But, I purchased a Walther PPQ M2 this week and took it to the range for the first time. I put about 200 rounds of aluminum case and 100 rounds of brass through the gun (a relatively light day of shooting compared to what we normally feed our guns) and had zero issues, the gun runs smooth and accurate with no malfunctions. But upon taking the gun apart i found a ton of aluminum shavings, mostly on the underside of the slide. I gave it a good cleaning and all seems okay, but when i fed home defense rounds into the gun it seemed to be chambering a little rough.Does anyone have experience with the aluminum issue? or is it a non issue if the gun gets cleaned well? And since im in experienced with hollow point ammo, does it typically feel slightly different to chamber a round?
