I made a few more variations for the "Panther", it is too much fun.
First, I "married" the "Lead Launcher" handle (part of a design I made for Gamekeeper John) with the Panther, simply by cutting the side bars off the frame handle and fitting it into a wooden handle. The wood is "cornus sanguinea", common dogwood. I wanted it to stay as bright as it is naturally, so I did not stain it, just polished and polycoated the whole thing.
I encourage every power hungry shooter to try this handle, it allows ridiculous draw weights. Here you see it equipped with four layers of TB Gold, a full butterfly set that propels the one inch (25 mm) steel balls to ridiculous speed.
I also made a very thin "Speznaz" version of the Panther, just by using a length of shrink tube to cover the handle. I outiftted it with a full butterfly set made from two layers of TB Gold, very good for the 20 mm steel ball ammo.
