Ah yes, the first ML hunt! I remember my first one. I thought for sure there was no way in heck that I could kill a deer with something so primitive. I didn't trust one gun so I had a TC Renegade in .50, a put together 12 ga loaded with patched roundball and a Ruger Old Army stuffed with conicals. I must have looked like Jerimiah Johnson, or an idiot, I'm betting the latter. Imagine my surprise when the smoke cleared and that Maxiball had dropped the doe in her tracks. I was amazed with that Renegade. Now I hardly shoot anything that isn't loaded with BP. I do all my deer hunting and most of my turkey hunting, CAS and trap all with BP.
Good luck on you first hunt and be sure to keep us up to date.
