If he used the powder I gave him, then it would have been Goex 3f. I'm 99% sure he used the powder I gave him but I'll ask the next time around. In any event, the wet patches were consistent with black powder residue and I will add ... there was no visual trace of any rust color on either of them. The barrel was clean enough after two patches to be shiny when looking through the bore.

I'm peeved about it but I don't think he caused any harm to the rifle. I'm certain of it. As I said before the climate is dry here and that would have helped also. So I'm not saying a person can get away with long periods without cleaning. I'm merely saying that the stainless is substantially more resistant than the blued barrels to corrosion. I don't know, but I really do think a blued barrel would have been substantially damaged. In my case, there was a $40 difference to go with a stainless barrel. I just think making that choice saved this rifle.

Im planning the construction of a 58 cal slow twist FL and a .54 cal fast twist CL and I'm planning both to be browned barrel rifles. I will definitely never loan them, except to maybe my son with modest oversight. I think I would lend the Kodiak Pro again though. This particular episode isn't going to keep me from introducing others to the sport.
