When I was a kid My dad took me hunting with an old double percussion shotgun. I can still remember the smoke and flames and the smell of the black powder.
When I got older (11-13) I would wait until dad left for work and then take it and go hunting. With some of the loads I poured down that gun I don't know how I didn't blow my head off. I can remember knocking myself out and waking up with a bleeding nose when I fired both barrels at once. I loved that gun.
About six years ago I bought a tc omega. After shooting it I was hooked. I have since sold all my centerfire rifles and replaced them with muzzleloaders. I no longer have any urge to fire any gun that does not spew smoke and flames
I love the smell of black powder, it's all I use. And I still have that old double 12.
