A good way to break in your barrel, have fun at the same time, and get to know a little about your rifle and how it works, is to get a box of cheap maxi ball. Lube them up and shoot the whole box off. You do not even have to care about accuracy. All your doing is knocking (if any exhist) the ruff spots off yourbore. After you're done use a good solvent that removes lead, when you clean the rifle and brush it good with a bore brush.

The do as the others suggested, load it up and bang away. I personally would shoot loose powder and 120 grains of Pyrodex or Triple Se7en and a 250 grain T/C Shockwave. You could even try some of the 200 grain.

As to the seasoning aspect why would you want to smear wax in your new rifle. In the modern steel it is not necessary, at least in my opinion. The only time your rifle should meet bore butter is if your shooting conical bullets. Sabots do not need bore butter..

Good luck with your rifle and keep us posted.. that's a great rifle you have there.
