Perhaps it would be best to check what calibres were available from the factory for your style of action (thick or thin side) and barrel shank dia. Any calibre other than those chambered by the Winchester Factory should be avoided.

The original action design was made for Black Powder cartridges, and although this rifle was made well into the Nitro Powder era, it is better to err on the side of safety.
