I would also recomend the old 44. My SBH is my constant companion I lad and cast my own so shooting it a lot is fairly cheep (just over $5.00 a box of 50).
I'm also a fan of Contender and Encore when I have to strech out the distance you can't beat a 30-30 for some one who doesn't reload.
One thing to remember is pratice is KING and when you think you are good enough pratice some more. Your max range is where you are able to put all 6 in a 10" paper plate not just once or twice but all 6.
Good luck have fun hunting with a Bow or a Pistol is king in my book.
