Used Hensley & Gibbs Mold. We believe this to be a No. 36, but the mold is not well marked. A nominally .360" diameter wad cutter design to be sized to .358" diameter. 158 grains based on information we could find on that mold number. Has Hensley & Gibbs marked handles fitted. Left handle has a crack starting on the collar and 1-1/2" long. These mold blocks are made in the U.S.A .Steel blocks almost never wear out, if properly stored.
