In light of the original post, this is a copy of my first deer rifle my father got me when I was a little kid.
It's an Uberti Baby Rolling Block Carbine single shot chambered in .357 Magnum. It will also fire .38 Special cartridges. It's a modern made, smokeless cartridge rifle patterned off of the blackpowder era 1871 Remington rolling block. When fired out of a rifle barrel, the .357mag is a very effective bush cartridge.
The carbine weighs 5 lbs, it has a .22" barrel, and is 35.9" in overall length. The recoil is enough for a 9 year old to handle. It harvests a North American whitetail deer and a western mule deer, no problem.
Many years later the carbine wound up in the hands of my uncle who had the chamber reamed out to .357 Maximum (an extended magnum version of the .357mag cartridge, it can still fire .357mag and .38spl), it was fitted with a Vernier tang sight, and was used in black powder cartridge shooting.
