I was wondering if anyone had some videos of wax build up in their bores? Many say that it does but I have only seen videos of lead deposits. I have just started waxing slugs and think that it is a little easier to clean, but I still have to pull a patch to get the lead out, and the accuracy is right back after a patch. If wax is building up, I certainly can't tell by looking at the patch, what's showing up on your borescopes?
