Fellow enthusiasts,
Thank you for the kind words.
Steel Horse Bailey,
Haven't taken any photos to date. I plan to in the near future though. Other original b.p. cartridges I have dissected are .32-20, .38 Special, .38-40, .44-40, .45 Colt & .45-70. Interesting history.
Grizzly Adams,
Good idea. I did try a 28 gr. charge of Swiss FFFG and it was almost 100 f.p.s. faster. After thinking about that a bit, I reasoned that is understandably so since Swiss is considered a Sporting Type of black powder (see below). Come spring I will be testing Schutzen FFFG and Goex FFFG. I'll post my results then. I'm thinking SWISS FFG would duplicate the original .44 Henry ballistics since there is over 100 f.p.s. difference in velocity between that and Swiss FFFG in testing the two powders in the .44-40 cartridge.
Interesting info on b.p. powder types by Bill Knight written before SWISS was imported into the US. Swiss is considered a Sporting Rate b.p. Bill is aka The Mad Monk, and, most recently, aka Dutch Bill
Powder Types.
During the 19th century a black powder shooter had 3 types of black powder available. These being: Sporting type, Rifle type, and Musket type. Today, the shooter in the U.S. has available one brand of musket type powder and one brand of rifle type powder. I should point out that type of powder has utterly nothing to do with grain size. It is not uncommon to find those who think that the difference in powder types during the 19th century was nothing more than grain sizes. In actuality, each type was formulated and processed to yield a specific burn rate and therefore specific ballistic strength. The ballistic strength having, at that time, been described as "expansive force". Each type was best suited for use in a particular range of calibers.
Sporting type - This was the fastest burning of the three types of small-arms black powder. The fast, "hot" burning sporting types gave diminishing returns at about 1 grain (volume) per caliber. In effect, 45 grains in a .45 caliber bore. It is about 10% hotter (faster) than the Rifle type b.p. Sporting type powder was usually found as an equal mixture of our present 2f and 3f sizes.
Rifle type - Somewhat slower in burn rate, rifle powder give diminishing returns above 1.45 grains per caliber. In effect, 60 grains in a .45 caliber bore. It has a ballistic strength about 10% greater than the Musket type powders. Rifle powders were also usually an equal mixture of 2f and 3f.
Musket type - The slowest burning of the three, musket powder gives diminishing returns above 1.6 grains per caliber. In effect, 70 grains in a .45 caliber bore.
Tuolumne Lawman,
Thank you for the additional info.
