I bought a air kit from kyle623 a few weeks ago . We'll today I made time to install and use. All I will say WOW just Wow !!! After a slow start adjusting as I went I ended up with the heater set at 85 and the air pressure at 35. I use Carnauba Red. Was able to size 800 boolits just as fast as I could drop the boolit and stroke the handle!! So if your in doubt just spend the money and you Will Be HAPPY!! Clint
