Drug the chronograph out of the basement to test some loads. This time of year at the Thumbcocker compound I hold tryouts for which Ruger .44 is going hunting in November. Mrs. Thumbcocker was gracious enough to record the readings and hid her absolute fascination with the science of ballistics behind eye rolls and sighs.
The guns: Ruger Bisley 5.5".44 special. Started life as a plow handle but was converted. Ruger Bisley .44 special 4 /58" one of my favorite specials. Ruger Bisley 5.5" .44 magnum. My favorite all around sixgun although the specials are gaining ground. Rugher Bisley hunter model 7 1/2" just a pure deer killing machine. The heavy barrel helps with recoil and I even kida like the red insert front sight in the woods. The last 3 guns have had the cylinder gap set to minimum.
The boolis: The Keith is from a NOE mold that clones the Hensley and Gibbs 505 and is cast of ACWW. The 265 RNFP is from an NOE Ranch Dog clone with conventional lube grooves. It is cast of WDWW. The Devastator is a Mia penta hp cast of 20:1. All are sized .431 and lubed with Ben's red. Wolf large pistol primers were used.
