All speed shooters load as lite as load as possible. I once raced a friend mine double action against his 1911 six in mine six in his. My load in 38 cases was running around 920fps 158 SWC. His a 200 SWC. I was done before his last case even came close to hitting the ground. He couldn't believe he got smoked. He still tells people at work and the club he lost.
