BTW, I also have the Ruger Buckeye Special in 10mm/38-40 & I love that gun!!! And to clarify my load testing data on 10mm vs .41 mag, I am using a 220gr LFN LBT Hardcast bullets in my 41 mag. Also use a 250gr WFN LBT bullet but they just have too much recoil! I might as well step up to my Ruger Custom Clements Super Blackhawk in 44 mag with 280gr or 300gr WFN LBT bullets if I want a heavier load with less recoil. My Model 57 S&W is much lighter than my Super Blackhawk 44, thus more recoil. And the 10mm load using 200gr XTP bullets & AA-9 is much more managable on the recoil out of my Glock 20. Not to mention 1 magazine carries 15 rounds....
