    Very nice mould. Classic Keith design. Cast a little hotter @720°F for perfect bullets.

    Ran mold 6/20/2020, Washed operating surfaces with tooth brush and Palmolive dish soap. Sparingly lubed locating pins, swivel and stop pin. Molded Linotype alloy.

    Scrap was high. Ran 100 bullets after warm up, kept 47 of them. Scrap was due to knit lines and small unfills in the nose and major diameter areas, which occurred from start to finish through the casting session. Some of these occurred even though the base of the bullet was frosted.

    Bullet diameters ran quite a bit oversize, from 0.433″ to 0.435″ with about 0.0005″ additional variation for concentricity. I had hoped for the mold’s rated size, 0.432″, as I was going to size to 0.431″ diameter. This mold leaves a lot more material to be forced through the sizing die than the recommended 0.0005″ to 0.001″ size reduction.

    Bullet weight varied widely, from 220.2 gr. to 224.5 gr., which is way low to the mold’s 260 grain nominal weight. From the density data I was able to find, a 260 grain wheel weight bullet should cast at 250.3 grains with Linotype metal.

    This is my second brass mold, and the other one did not run well either. Starting to wonder about the suitability of brass as a mold material.

    All in all very disappointed.
