For about 15 years, starting in the early '90's, I used only traditional guns, cap and flint, to deer hunt in all firearms seasons. It started when I moved to a shotgun only state (Indiana), and quickly decided a muzzleloader was a better choice for me, having started hunting with centerfire rifles. I even adopted it for my out of state hunting.
Over the years , my Indiana hunting buddies moved away, and I was down to Kentucky hunting only. I went back to bolt action centerfires and optics, and found them to greatly enhance my shooting, mostly due to the optics. A few years back, I picked up a Knight Wolverine out of a closeout bin at a local archery shop, and discovered how handy and accurate it was.
I still have the Traditional guns, but I know at my age, I am better off using a scoped gun when I intend to kill something. I figure I owe to the animal.
