I think a 45/90 is far more practical than 50/110, 475 Turnbull or 450 Alaskan. Originally the 45/90 was an express cartridge and a lot of the 1886's in this caliber had a slow twist for light bullets over heavy doses of BP. Just make sure you get one with a twist fast enough to stabilize the longest bullet you are likely to use. The other factor is to make sure you get it in the right configuration. 1886's came in a wide variety of barrel /magazine/ grip/ buttstock configurations which can affect handling if you intend to hunt with it.
