Excessive Fouling in my Cabela's .50 Hawken 1:48 twist

[Coinneach]

I have an older CVA that was a police auction gun. No telling how long it sat in an evidence locker with the bore slowly rusting. It was pretty bad when I got it and I figured worst case, I'll have Bobby reline it. I did the Scotch Brite thing and a pass with some valve grinding compound followed by a thorough cleanup. I call it my sewerpipe on a stick. It's an ugly duckling for sure, but it's a great example of how a bore can be salvaged to useful status. It's now one of my round ball teaching guns. And here's how it shoots with my custom minie for 50cal.

Well many a sewer pipe polished up a tad became a successful career politician, so why not a Rifle ?

That is I started with .490 ball and eventually worked up to a .018 patch using mink oil, same result. So polishing the bore some more may be the issue or change the patch lube.
