.40-90 Sharps (Straight) Reloading Data

Warning! Notes: The so-called "Everlasting", or reloadable case, was popular with hunters and target shooters during the 1880-90 period. These heavy cases could be reused repeatedly. In fact, they were made so heavy that powder capacity was often reduced by 5 or 10 grains. To get around this, the "Everlasting" case was often made longer than the standard. UMC cases of 40-3 1/4 inch caliber are usually of very heavy, reloadable construction. The reason for mentioning this is that it might have a bearing on the origin of this cartridge. Physical measurements of the so-called 40-90 Sharps Straight are practically identical to the 40-90 Ballard, except for the length. It is possible that the design of the 40-90 Sharps straight is based on lengthening the Ballard cartridge to create an "Everlasting" version with the same capacity and ballistics. Anyway, the idea is worth mentioning and would probably occur to anyone who compared the two. Although longer, this case has the same basic body as the 444 Marlin. It should be possible to make usable, albeit much shorter, cases from those. These rifles had a chamber cut to use a bore-diameter (0.403 inch), paper-patched bullet; groove diameter was 0.408 inch to 0.411 inch. (Cartridges of the World 9th Edition)
