[3] The new 45-70-500 loading was recorded with a muzzle velocity of 1315.7 feet, and generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards ...
An open single-cavity bullet mold and a closed two-cavity mold. A cast bullet is made by allowing molten metal to solidify in a mold.Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity.
Bullets had the manufacturer code over the Quarter number and two-digit year of production engraved on the base (e.g. Pk/2-26 is Zaklady Amunicyjne, Pocisk, 2nd Quarter of 1926). 8mm Lebel "Balle D" bullets were differenced from 7.9mm Mauser bullets by a capital letter "D" inset between the contractor code and the date (e.g. Pk/D/2-26).

Even the guy at S&W who developed the .500 and .460 thinks the .460 is a better hunting cartridge (see here ).
Derived from the .50-60-400 Joslyn, the cartridge was developed after the unsatisfactory results of the .58 rimfire cartridge for the Springfield Model 1865 rifle.

It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, [4] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun.
