Scrounged up some descriptions for .320 / .321 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]

321232 Standard bullet for the .32 Winchester Special and Marlin .32 H. P. The first groove is a dirt catcher, or for lubrication. For tubular magazine rifles case should be crimped in second groove to prevent bullet receding. This bullet is also the best bullet for single shot .32-40 rifles where bullets are to be shot from case. It is fine for such .32-40's as are worn a trifle large. Load with several bands projecting from case and size to .321". Use 13 to 15 grains Du Pont No. 80 powder. (GC, FN, 170 TP is 295)
321265 Express bullet for same use and with same charge as 321232. In .32 Winchester Special rifles this bullet is fine for deer, and the load will not wear the barrel. Also in .32-40 single shot black powder rifles it is a splendid bullet for woodchucks. (PB, FN, HP, 153 - TP is 295)
321297 Splendid gas check bullet for .32 Winchester Special and .32-40 single shot rifles. With two moulds hunters can make their own hard or soft point bullets. The proper powder charge is 21.5 grains weight of Hercules Lightning powder. Extremely accurate, and does not wear out the barrel. In .32 Winchester Special tubular magazine rifles muzzle of case should be slightly crimped into front groove to prevent bullet receding into case. This bullet also for use with 8 m/m Lebel French army rifle. Use charge of 22 grains of Lightning. Size to .321. Gives velocity of about 1500 ft. seconds. Tip molds for two-part bullet were available. (GC, FN, 181 - TP is 295)
321298 Standard bullet for .32 Winchester Self-Loading rifles. Cast 1 part Tin to 15 of Lead. Crimp muzzle of case slightly into bevel groove. Use No. 10 tool with double adjustable chamber. (PB, FN, 151 - TP is 295)
321317 Standard bullet for rifles using the .32 Rem. Auto. Rimless cartridge. Powder charge 21 to 23 grains Hercules Lightning. Crimp in bevel groove, and size to .321". (GC, RN, 161 - TP is 470)
