K-Law, the first 4-gun hydro Mec set up I ever saw belonged to All-American/Hall-of-Fame Skeet shooter Grey Silva. He was a diminutive man and almost 80 years old at the time -- not quite out of the Big Jim mould.
Grey was one of Skeet's true gentlemen and I consider myself fortunate to have known him. He was at the club shooting every day. One of the members fondly commented, "When does he find time to reload?" Perhaps Grey's hydro system made his high volume shooting possible.
