Scrounged up some descriptions for .264 diameter molds from a variety of sources. If some of you-all have better descriptions from Ideal or Lyman catalogs, please post to this thread with the correction or description of the boolit..
Disclaimer: It is well known that (at times) cherries have been used too long, with undersized cavities resulting. Some throats are too big compared to the groove diameter. Over time, manufacturers held different tolerances and dimensions for the chamber and bore. Different alloys will turn out different diameters. What follows below is simply a collection of the various Ideal and Lyman mold descriptions, which does NOT mean that any particular mold will cast a boolit like you expect. What does this mean? Slug your bore if you don't know the bore/groove dimensions for your gun. If the mold is undersize, you may have to beagle / lap it out some. [ed]
NOTE: Any loads mentioned are taken from period documents, and are not in any way tested. Please refer to modern loading manuals for safe loads. [ed]
