Evil Roy: “Vihtavuori powder is the best”

Evil Roy – Overall World and Overall National Champion Cowboy Action Shooter – is one of the icons of the sport. Evil Roy says Vihtavuori to be the best CAS reloading powder at the market.

I have used Vihtavuori gun powder for several years in all my Cowboy Action firearms. It is very clean burning, very consistent in velocity and has soft recoil. The new Vihtavuori Cowboy Action Powder will be even better suited to our sport as it is especially designed for the large cases and small charge weight we normally use.
