I have some soft paste wax, including neutral shoe polish that I normally use as a release compound for epoxy-bedding (best ever). I'll try them both, to see if there's any difference in velocity or fouling in my .270. Barnes TSX bullets were the worst at fouling my barrel, but I don't have many left, so I'll try the Hornady GMX first.
If I can't be with the rifle I love, I love the rifle I'm with!!
