Now that's funny.. I had the same sight up, selected the same rifle. And a matching 1-32 twist .50 caliber barrel for it. Was about to hit the submit button and was able to talk myself out of doing so. Glad you did not talk your self out of it. You are going to love the rifle. My friends shoot them and they are awsome to shoot.

They take a 5/8th Thomas Fuller Black English Flint. They come with a Lyman Agate which is a great stone. It will give you about 45-60 shots before you need replace it. Be sure and shoot black powder. 90 grains of Goex 2f and a .530 or .535 ball will work just fine with a pillow tick patch. Good luck. Glad you bought one and I did not...
