When i "seasoned" the bore in my deer creek i just let it sit out in the HOT sun and when it hurt my hand by tring to pick it up, i ran a doped up patch of bore butter down the bore, Worked it up and down the bore for a few strokes and then let it bake some more before running a few dry patches. I no longer due this, i dont even oil my bores in any of my muzzleloaders.
