A carbine makes a good heavy woods hunting rifle in the .50 or .45-70. I always wanted a .50 Sharps Carbine and I have passed up a couple but they were more of a .52 cal. When I was a Kid back in the 50's I bought a roller in the .43 Spanish caliber for $14. out of the back pages of the NRA magazines. I couldn't afford a $25-28 dollar Sharps stacking hay bails in a hot haymow for .50 cents an hour all summer long laugh so I got the roller. Been hooked on these old rifles ever since.
That Trapdoor carbine in the photo was a rifle that had bad erosion at the muzzle from the cleaning rod use and a bad dent down a little farther from the muzzle so I chopped it off and it turned out being a fine hunting rifle for the Michigan UP woods I used to hunt in.
