I too have a Lyman Great Plains in .50 caliber. I got it in kit form for Christmas 1984 from Mid South Shooters Supply for the grand sum of $125. I browned the barrel and did a decent job on the stock. I love the traditional design and could not afford the Browning Hawken. It's a great round ball gun and has the slow 1 in 66 twist (if I remember correctly).I've tried the Mine' balls with little luck. I made my own hunting bag, ball blocks, patch knife, and powder horn to go with it. I also have the bullet mold and love melting lead in the fall. One of my favorites and one of my favorite Christmas gifts.
