I will have the Bobcat in my hands next weekend hopefully, I already have a dedicated r/b shooter (.45 Deerhunter 1:66) and are planning to build a .54cal ballgun.
A friend made me a custom .54 barrel, 1:56 twist with rounded grooves(Henry rifling or something) with a double trigger and hammer. Only needs a stock but need time to build it in the near future, still deciding on whether I'm gonna scope it or use open sights. That will determine the stock's shape/design.
