Re: just got a tc hawkens flintlock a few questions
That would be what I would use. When I shot my 45, I used .440 round balls and 70 grains of 3f black powder. Worked very well for me. I know it's kinda short notice for the season but just experiment and good luck!
Edit: Starter kit... I don't think I would go with a starter kit. Usually the stuff that comes in the kits can be found for a reasonable price at better quality. Read up on the different things you will need and piece yourself together a kit. Most of my stuff is homemade. My short starter, my bags, turkey call cases for flint holders, a safety pin for a vent pick. The only thing I think I really purchased were 50 cal speed loaders and my flask.
A bad day hunting rabbits beats a good day of anything else!
