I'm looking to pick up a Civil War carbine to both collect and shoot. What is the best choice from a shooting aspect? I have a Spencer with a centerfire breechblock and I'm working on reloads. I also have a Sharps converted to 50-70 that is very accurate and I already reload 50-70 for several rifles. From what I have read it really leaves a Smith, Burnside or a Maynard as the easily obtainable shootable carbines. What is your opinion and why? Thanks in advance for any help.
