These rifles came in a variety of chambering's.
What chambering would be the overall recommended one?
What was the most popular one that carried the best reputation
back in the day? I would be looking for ease of casting and loading
with original hand tools and of coarse BP.
Thanks, Mike

"The 1876 was introduced to celebrate the American Centennial, and earned a reputation as a durable and powerful hunting rifle. Production included 54 One of One Thousand Model 1876s and only seven of the One of One Hundred grade.[4] Originally chambered for the new .45-75 WCF cartridge (designed to replicate the .45-70 Gov't ballistics in a shorter case), versions in .40-60, .45-60 and .50-95 Express followed; the '76 in the latter chambering is the only repeater known to have been used in any numbers by the professional buffalo hunters.[6] The Canadian North-West Mounted Police used the '76 in .45-75 as a standard long arm for many years with 750 rifles purchased for the force in 1883;[7] the Mountie-model '76 carbine was also issued to the Texas Rangers. Theodore Roosevelt used an engraved, pistol-gripped half-magazine '76 during his early hunting expeditions in the West and praised it. A '76 was also found in the possession of Apache warrior Geronimo after his surrender in 1886."
