Scrounged up some descriptions for .245 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]

.236 was at one time supposed to be the proper diameter of bullets for the new U. S. Navy Rifles, but now the rifle and cartridge is called the 6 m/m. U. S. Navy, and the proper diameter of the bullets for that rifle now is .244.

.23639 Experimental for .236 U. S. Navy (PB, FN, 45, 65, 75 – TP 415)
.23640 Experimental for .236 U. S. Navy (PB, SP, 50, 56, 63, 70, 82, 94 – TP 450)
.236199 Experimental for .236 U. S. Navy. (PB, SP, 31, 38, 45, 53, 60, 68, 83, 90, 98 – TP 450)
.244203 These are the only cast bullets that are correct for the 6 m/m U.S. Navy Rifle; 65 grains is for short range; 95 grains for medium. (PB, RN, 65, 95 – TP 203)
.244253 Looks similar to 236199, probably multiple weights. (PB, RN, 65 - TP 450)
244305 Ball (?)
245496 Designed after H. Guy Loverin design. Very popular for both the 243 and 244 calibers. (GC, RN, 85 - TP 203)
245497 Made as an experimental design for the 243 and 244 (GC, RN, 93 - TP 203)
245498 (GC, FN, 99 - TP 498) .22-10-45: Hello, madsenshooter. You are spot on in that the 245499..and particularly the 245498 are well suited to the 7 1/2" twist of the .236 (6mm) Lee-Navy rifle.
245499 Made as an experimental design for the 243 and 244. Thus far has proved very poor as it is too heavy. (GC, RN, 110? - TP 203) madsenshooter: it also ought to make a good bullet for the 6mm Navy as it has a fast twist that would stabilize it.
