On a side note... there were alot of large caliber buffalo calibers ... but alot of them might be what we would call "wildcat" calibers today. Here are a few that i know... .40-90, .40-100 Sharps (Necked), .44-77 Sharps and .44-77 Remington, .44-90, .44-100, .44-105 Sharps (Necked) and .44-90 Remington, .44-100 Ballard and .45-100 Ballard, .45-70 Government, .45-75 Sharps (commonly mis-called the .45-70 Sharps), .45-75 Winchester, .45-90, .45-100, and .45-110 Sharps (Straight), .45-120 and .45-125 Sharps (Straight), .50-70 Musket (.50 Government), .50-90, .50-100, .50-110 Sharps. Most of these calibers are by far extinct... not having any ammunition being made for over a hundred years in some cases. I'll take a picture of my 45-110 and post it soon...
