The Winny is probably a little light for the recoil of a full gin Lott. Shortening the barrel isn't going to help that and adding weight to the rear fools with the balance. And getting it to feed Lott cartridges can be problematic. Not all gunsmiths can handle that.
The CZ is built on the magnum action so it is a little oversize for a H&H cartridge and the stock is bulky and clubbish to me.
I would probably talk to American Hunting Rifles about what I wanted. They are the CZ experts and can advise you.
