Greetings!
I have four or five of the Winchester 1894 Reloading tools; none of them had the factory decapping rod with them, but they're easy enough to fabricate.
At the top of the Die, there's a tapered nipple; that gently flares your case neck for starting the bullet. Lubricate the case. Once you've primed your case, and dropped your powder charge, start your bullet into the neck of the case, and carefully insert the assembled cartridge into the body of the Die. Screw the Die into the Reloading Tool as far as it will go without force. Press the Reloading Tool Lever, and screw the Die deeper into the Tool; press the Lever again and screw the Die in further, repeating the above until the Die is screwed fully into the Tool. To eject the loaded round, pull the Lever, and unscrew the Die; the loaded cartridge should fall out. I've assembled .45-70 Govt. cartridges using the Winchester 1894 Tool. I've seen printed instructions, but I'm at a loss where; perhaps in a circa 1890s "Shooting and Fishing"...
