OK guys, after about 30 rounds with the XDm-9 today, I noticed something I hadn't seen before...at least not to this extreme. My bullets normally drop out of the Lee mold at .357-.358, and I have experienced little to no leading. In the first and third photo looking down the front of the barrel, it appears to be little leading. But in the second photo, looking at the end of the barrel...is that leading or bullet lube? This appears only at the last 1/3 of the barrel. My understanding is leading show up like fibers? this looks more "caked" on. BTW it does come off very easily with Chore Boy copper.
