.375 mold descriptions for Lyman / Ideal molds
Scrounged up some descriptions for .375 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]

.38-55 Cartridges (from the Ideal 1929 Catalog)
.375" is supposed to be the standard for all .38-55, .38-56, .38-70, and .38-72 rifles. As a matter of fact almost all of these rifles have a groove diameter of about .379" and as a rule, particularly for use with smokeless powder, these bullets should be sized to that diameter, being cast large enough for this purpose. The .375 Magnum rifle, however, has a groove diameter true .375", and bullets intended for use in that rifle should be sized .375". It should be noted that the .38-55 cartridge is really misnamed. Originally the cartridge would hold 55 grains of black powder, when made with very thin head case, but afterwards the case was thickened, and these cartridges have a black powder capacity of only 48 grains when a 255 grain bullet is seated to standard depth.
.375 is the correct diameter of bullets for all arms using the very popular cartridge .38-55 Marlin. This cartridge was first originated by the Marlin Fire Arms Co. and has been adopted by nearly all other makers of rifles. .375 is also correct for the following cartridges: .38-56, 38-70, .38-72, .38-90. The shape of bullets for all of these cartridges is the same as the .38-55-255 (except the .38-72, which has round point), and will interchange and seat properly with the regular tools.
37576. This is the standard .38-55-255 bullet. It will seat correctly in tools for above cartridges. One band off is the regular .38-90-217 Winchester. (PB, FN, 217, 255 – TP ?).
37577. Express bullets. They add greatly to the killing powers. The .38-55 rifle with express bullets are sure killers of deer and elk. These bullets are of the standard shape and will seat correctly in the regular tools. (PB, FN, 235 HP – TP ?)
37578. This bullet has one wide, deep groove for lubrication and two strong bands. It is claimed to be an accurate flier, also that it will not strip and lead the barrel if shot at a higher velocity. It has a round point similar to No. 37581. (PB, RN, 260, - TP 167)
37579. This series of bullets has many friends. They have wide, deep groove, point is short, making nice, light weight bullets. (PB, FN, 135, 170, 205, 245, 285, 325, also Perfection – TP 449)
37580. Excellent reports come from this bullet as a very accurate one. It was designed by a sea captain, and has been used successfully in shooting large fish. (PB, SP, 125, 167, 214, 250 – TP 80)
37581. This bullet is similar to the standard .38-255, except that the point is round, same shape as No. 37578. (PB, RN, 253 – TP 167)
37582. This is a fine short range bullet, and requires a special chamber to seat it. (PB, FN, 170 – TP 449)
37583. Regular .38-55 short range bullet. Powder charge 20 grains Fg black powder or 7 grains weight Du Pont No. 80, or 5 grains Hercules Unique. (PB, FN, 145 – TP 449)
37583S. For use in 36 Colt cap and ball revolvers. Use 20 grains of FFg powder.
37584. This is a popular series of bullets for both short and long range. The shape of point is standard. They seat all right in the regular tools. (PB, FN, 156, 176, 187, 218, 238, 259, 280, 301, 322, Peerless – TP 449)
37585. This is a fine series of sharp pointed, heavy and light weight bullets for .38 caliber rifles, and also the .375 Magnum. They are very accurate when seated with several grooves outside the case so that they extend up into the rifling. With the lighter ones, squirrel and other small game may be killed without mangling. Perfection moulds are not made for sharp pointed bullets. Powder charges should be 8 to 13 grains Du Pont No. 80, or 4.5 to 7.5 grains weight of Hercules Unique, depending upon weight of bullet. (PB, SP, 116, 141, 166, 192, 216, 242, 262 – TP 376)
37586. This bullet was designed by the Zettler boys, of the Zettler Rifle Club, New York City. It has many friends. It is not the same diameter the whole length; the three base bands are .005 of an inch above the standard size, so they cannot be seated in the regular shell without being sized. (PB, FN, 265 – TP 449)
37587. Round ball, for light charge of powder, for small game, short range or indoor practice. Too much powder will cause them to jump the rifling; with proper quantity they shoot very nicely. (80)
37588. This is the famous Rabbeth bullet. It is a record maker and is used with Chase patch. Cylindrical mould only. (PB, FN, PP, 330 – TP ?)
37589. This is an illustration of bullet from Cylindrical adjustable mould. Bullet is cast smooth for paper patching. Mould will cast bullets of varying lengths, with flat, round, or Leopold point (PB, RN, PP, ? - TP ?).
375163 (sometimes listed as #370163) Shown as "38 Carver 330" (PB, SP, PP, 330 - TP is ?) Boolit Bub: Oh it is #370163, they just switched the recommended sizes around over time. Cherry #163 was never assigned to anything else. They used to do that quite a bit without actually changing much of the physical dimension of the bullet.
375164. Designed for the .38-45 Ballard. (PB, FN, 190 – TP 449)
375165. Designed for the .38-40 and .38-50 Remington. (PB, FN, 250 – TP 449)
375166. This is the factory .38-330 grooved bullet. It is used with a shell full of powder for target work. (PB, FN, 295, 330 – TP 449)
375167. Standard bullet for the .38-72-275 Winchester Model 95 rifle. Cast 1 to 16 Tin and Lead, and size to .379”. A fine bullet for target or any American big game. The .38-72-275 was a most excellent black powder cartridge, but it never had a chance for it was introduced just before modern high power rifles came in vogue. Powder charge 72 grains Fg black powder or 20 grains weight Du Pont No. 80. The point being round, it requires chamber to fit it. (PB, RN, 275, - TP 167)
375200. This bullet was designed by riflemen who attend the well known “Walnut Hill Rifle Range” near Boston. It is intended especially for fine target shooting. The points are one band shorter than the standard, and are usually set in barrel with bullet seater. They will, however, seat in the regular chambers of the .38-55 tools, crimping in the forward groove; best results, however, are obtained when shells are uncrimped. No. 3 tool is recommended. (PB, FN, nose or base pour, 132, 153, 177, 195, 215, 237, 256, 300, or Perfection - TP is 449)
375211. The 179 grains weight is one of the finest short range bullets made for the .38-55 rifle, and the 265 grains weight is fine for full charge. It is a killer. The strong bands hold well to the rifling. The regular tools seat them. Designed by Kissler. (PB, FN, 179, 265 - TP is 449)
375248. Standard bullet for .38-55, .38-56, and .38-70 Winchester. For tubular magazine rifles case should be crimped in forward groove. Good for other 38 calibers. (PB, FN, 255 – TP 449)
375262. Express bullet similar to 375248. The hollow point increases its killing power making it an excellent deer bullet. Use same powder charges and same style of loading as 375248. (PB, HP, ? - TP is ?)
375272. This is the famous Schuetzen bullet designed by Dr. W. G. Hudson, which gives such remarkable accuracy in .38-55 rifles which have been specially throated for it, the bullet being loaded into the bore ahead of the case. 5 bands, front three bands .372, bottom two bands .382 (PB, FN, 310 – TP 449)
375296. For .38-55 High Power rifles having nickel or smokeless steel barrels. To be cast of Ideal Alloy, or 1 part Tin to 10 of Lead, and sized to .379”. Hunters with two moulds can make their own hard or soft point bullets. (Illustration shows separate tip mould). Crimp case in forward groove for use in tubular magazine rifles. Very accurate up to 500 yards, and an excellent killer on large game. This bullet will not wear out the barrel. Excellent game bullet for other 38 calibers such as .375 H. & H. (GC, FN, 265 – TP 449)
375300. Three front bands cast .368, two base bands cast .378 (PB, FN, 270 – TP 449)
375313. Plain base lightweight bullet for .38-40. (PB, FN, 190 – TP 449)
