Oh no! Not the seasoning vs. non-seasoning thing again.

All I can do is report my personal experience. When I got my new GP, I cleaned the bore real well with patches soaked in regular rubbing alcohol - then started shooting with round balls and lubed patches. I got accuracy as good as I could expect with those factory buckhorn sights and my bifocal eyes.

A good place to look at various supplies is the RMC Sports web sight.
