I have several lever action rifles, including an Uberti replica of an 1873, in 44-40. I am very happy with it, but it has a 28" octagonal barrel and is very heavy. I am thinking about getting a 16' barrel carbine. I have a 1894 Marlin and a Rossi replica of an 1892 Winchester in 357 Magnum. I also have an assortment of other Winchester and Marlin lever actions in various other calibers, including several 1894s. I really like the 1873 action and I am inclined to buy one in 357 Magnum because I have more 357s than 44-40s and have a lot more ammo on hand. I reload both calibers, but find that with the carbide dies, 357 is a lot easier. I have been told that the 1873 is marginally safe for the .357 magnum and that the 44.40 is a better choice. But I would be very interested in any knowledge or experience any one here can give me.
