I am trying to figure something out- headspace measurements on 9mm cylinder when installed in Blackhawk.
If any of you have feeler gauges, a .357mag Blackhawk convertible model and some time, could you makes some measurements for me?
Specifically, can you use the empty 9mm cylinder, installed in frame, pulled to rear of frame [hammer end?] and measure the gap between the cylinder and the recoil shield under the hammer? No ammo/snap caps installed at time of measurement, please.
I would appreciate measurements in SAE, instead of metric.
I know that Ruger has said a Super BlackHawk was supposed to have a measurement of between .060" and .066" in this area.
I know that the 9mm cylinder headspaces on the case mouth, and not the actual cylinder.
I am just trying to get this measurement from, hopefully, 3 different 9mm cylinders [that were factory fit] to see what to do with my 9mm cylinder.
I am trying to set up my bh as a convertible, but am not sure what is going on with headspacing.
Thank you in advance.
