I'm trying out some PD 185gr JHP bullets, and so far, I really like them. But in loading a batch of 200 last night, I noticed they're really dirty (thumb and first couple fingers on the left hand blackened) and they're covered in what I'm guessing is corn cob tumbling media. Most of them seem to have a few granules of media in the JHP cavity. I lifted the bag out of the box last night and there was so much media in the bottom, I had to wonder if their method of tumbling is pour media into the bag of bullets and let USPS do the vibrating. Is there an easy way to clean these up? I'm tempted to put them in the tumbler with some fresh media, but I don't want to make them worse. I was chronoing some of these (and some Precision 200gr) yesterday, and basically shot out the bullseye of the target I had beyond the chronograph...so the left over lube (I'm guessing that's what it is) and media don't seem to be causing any accuracy problems. Has anyone compared these and Zero's 185gr JHP? The Zeros are actually a tiny bit cheaper, but out of stock where I'd normally buy them.
