Look at the stock you can get for the Savage.
Damn that would look good on my rifle. I am saving my nickels.
Richards Microfit does not make stocks for muzzleloaders per se, they make them for prominent bolt guns. You can get one for the 98K Mauser. You can get one for the Savage bolt action rifle, which also fits the muzzleloader.
