Neither

I use Birchwood-Casey Barricade (formally called Sheath)which dries leaving a protective film that doesn't attract dirt. After cleaning my gun I run a patch sprayed with Barricade down the barrel and put the gun up. You don't need to run a dry patch because there is nothing to dry and remove from the barrel. When I am ready to use the gun I just poor the powder down the spout and load it - no need to run a dry patch.

I don't use oil in the barrel because Oil + fire + black powder residue= TAR, and I don't want tar in my barrel.

There is a divergance of opinion about Bore Butter. Personally I think it is a joke.

Greg Ritz, in the DVD that came with my OMEGA, says that the OMEGA is a high tec modern muzzleloader, made with the most advanced componants andcapable of shooting a high-tec saboted projectile out to 200, even 250 yards. He then turns right around and implores us to use Bore Butter to protect and "season" our the OMEGA barrel. Which is it Greg??? - A high Tec gun or a cast iron skillet??? I want to shoot animals with the gun Greg, not fry chicken in it. Exactly how does that Bore Butter "season" the barrel Greg? Show me the objective evidence supporting that statement. What's in that "Natural Lube" anyway, whale blubber, lard, chicken fat, bacon grease?? What is so "Natural" about it and why do we need it in our modern T/C muzzleloaders.

If this "season like a cast iron skillet" statement actually has merit, why don't we do it routinely with centerfire rifles??? Is Greg advocating that we use bore butter for the new T/C Icon???
