I have two renegades a flint and a percussion both if .50 Both are great guns and can be found for a reasonable price. If I were you I would buy a .50 if I found one for a good price and you can always get a gm barrel later.

I haven't shot a lyman, but I've heard good things. I bought an older cva percussion gun in .50 and it turned out to be one heckuva shooter with conicals.

Keep an eye on the auction sites and check your local shops. The inline craze has put alot of sidelocks in the used gun racks at decent prices.

You may as well go ahead and buy two, that should help with the addiction for a little while, but it won't be enough.

Good luck.
