Does anyone know what the powder charge was for the British 1796 Heavy Cavalry Carbine cartridge?
Wasn't the standard carbine cartridge around 55 grains?
No, I don't believe so. Subsequent to my original post I have been doing a bit more research and I'm inclined to believe it was in the 125-150-grain range. I shot mine the other day with 80 grains and it was a very light load--virtually no recoil at all. According to DeWitt Baily the standard Brown Bess load of the time was in the 200+-grain range. The 55-grain load would have been appropriate for a later .577 Minie cartridge for something like an Pattern 1856 Enfield Carbine. Thanks for your interest.
Those original cartridges in the article I read must have been later then.
I always thought that one of the advantages of the 1796 pattern was it’s calibre commonality with the Land and India Pattern Muskets. Would there have been .75 carbine cartridges at all or would normal Infantry natures be common to both? It certainly would ease an already complex ammunition supply problem.
I would have thought the full Infantry load from the shorter weapon would have been a bit fierce. Of course, in extremis you didn’t have to put it all in I suppose.
Perhaps the only way to be certain would be if we had an intact cartridge we could measure, but I would have thought them rare survivors?
@david Tomlinson Voila! Just this morning, in re-reading DeWitt Bailey's "Small Arms of the British in America 1664-1815" I found he states that a .75-caliber carbine cartridge load was 4 drams (110 grains). Allow 5 grains or so for priming and that means the propellant charge would have been just north of 100 grains. The musket load was 6 1/2 drams (178 3/4 grains.
