Much has been written about the down side of the YTC custom mold bullet maker. Its rear locking lugs, cock-on-closing action, and two-piece stock are blamed for its less than stellar accuracy and limited popularity among American shooters. Nonetheless, the YTC is capable of surprisingly good accuracy if in good condition and fed the right ammo. The low pressures generated with lead bullet reloads, put little stress or wear on these old rifles compared to factory or military ammunition from custom mold bullet maker.

Many military surplus custom mold bullet maker products arrived in the U.S. at the end of their useful life with seriously worn bores. Provided that the throat is not too severely eroded, most can be made to shoot correctly sized cast bullets quite accurately. Granted, starting with a tight, nearly new barrel would be preferred, but many of us purchased these firearms as war relics without benefit of micrometer measurements and are stuck with making do with what we have as custom mold bullet maker.

A throat- slug or cast should be made to determine the length and diameter of the area where the rifling begins and the chamber ends. Measurement of this area will determine the correct diameter of the bullet you'll need to use. It may also serve to qualify your particular gun as a wall hanger, rather than a shooter. Throat diameters over .316-.317 are probably too large for practical purposes but can still be used if you are willing to go to some extra trouble. Measurements of .312-.314 make bullet selection much easier as these diameters are commonly available. Rough, pitted, or corroded throats may need to be lapped with abrasives to smooth them out, further increasing their diameter of custom mold bullet maker..
