The fouling has been elimnated as the issue but thanks. I know I had it cleaned down to the bare metal and I still got a keyhole.
I did try the "non-match" Bergers and they are shooting just as well, same POI, and no keyholes. I'll just be loading all those up for now.
If anything I've discovered (after thoroughly cleaning this tube finally) that the .17 fouling problem is largely a myth IMO. You couldn't get a barrel much more filthy than this one. And it still printed nice groups as seen from the initial picks.
