Every muzzleloader seems to have it's own personality. I have owned rifles that could be loaded on a clean bore and put the bullet right on target, and I have had rifles that had to have a "fouling shot" before they could be hunted with.
If you clean the rifle and then oil the bore it is wise to at least wipe the oil out before loading. If you wipe the oil, snap a cap or two, then load and the first shot is on (or very near) the mark you are probably good to go if you follow that routine before you hunt.
But if that first shot is wild it could be your rifle likes a fouled bore for accuracy. If that is the case you should shoot at least a reduced charge before loading to hunt.

With my T/C Hawken all I need to do is run a couple dry patches down the bore, snap a cap (#11s) or two, and then load up for hunting. It doesn't need a fouled bore to put shot #1 very close to where I'm aiming. With my inline (Traditions) I need a fouling shot or the first shot will miss the mark by several inches.
Could be the reason I prefer the Hawken.
