RE: maxi hunters...
The T/C Maxi Hunters in 360 grain should shoot excellent out of your rifle with about 70-80 grains of Pyrodex RS. As for use as a hunting projectile you will find them excellent. If you hit a bone they do tremendous bone smashing damage. If you miss the bones they still put a 1/2 inch hole through the animal. You make sure that hole is in the vitals, and nothing can stand up to that. They usually always get excellent penetration also.
Another choice for your rifle if you have access to bullet casting supplies are the LEE R.E.A.L. conicals. They come in a 320 grain which would also work real well in your rifle.
Keep in mind, these are flat based conicals, and you will often get better accuracy if you use a wonderwad between the projectile and the charge. If you have no wads, some people use corn meal. I have never done that myself, but just for kicks I am going it get some and try it....
You have a great rifle there.......
