Hi all -
I've searched on here and found similar threads, but NOT one as specific as what I'm asking below.
1) I own a Glock 34 Gen4 (production 2012)
2) I'm a cheap shooter and I currently do not reload (another topic for another post)
3) If I ONLY shoot WWB or other inexpensive equivalent...
The other day, I picked up two WWB - 100 round 9mm at Walmart.
I checked it out at home and noticed many of the brass casing had dark spots all over them, and one had a spot of heavy corrosion.
Anybody else experience this? Know why this is happened?
