Actually 1 in 60 ain't too slow for the Minie. The original 1855 Rifles and Rifle-muskets were grooved 1 turn in 6 feet. The pistols were grooved 1 in 4. Experiments were made with
progressive twist, but it was found that the bullet wanted to strip.
As for the 2 banders being "too short for line infantry" as one of the earlier posters said, I can only agree with VA Man. 06 and some others. Most of the contract arms actually manufactured in the Confederacy were 2 band rifles. Not to mention all the Austrian Lorenz and Jaegers, Enfield Sergeants rifles, etc. Reenactors have a nasty habit of not presenting their pieces according to the Manuals, especially while oblique firing and my old unit was one who phased out the short rifles because of this as well as for the sake of uniformity. I'm sure the same thing happened during the War with inexperienced and excited troops. But remember, the rifle's barrel was only 7 inches shorter than the rifle-musket's, 9 inches shorter than the rifled musket (example: 16's and '42's). That's not a big deal if you watch what you're doing. It can be if you don't. The biggest problem is cap flash and cap fragments. That's where the biggest danger is, and that happens no matter how long the gun is. That cap is LOUD and those fragments do sting!
Joe P. you make some good points there. A lot of surplus made it's way to the farmers both East and West. Cheap reliable weapons. Hundreds of thousands of muskets as well as repeaters also made their way back to Europe being sold to France to use against the Prussians in their little spat and also to "Third World" countries in Africa and South America. In fact, I've read that is where most of the Zouaves went after being smoothbored in a larger caliber. Supposedly they were made into trade guns. Apparently quite a few remained here, but you would think there would be more around.
I guess after the War was going on for a while, the North pretty much armed their cavalry with breechloaders and repeaters, but early on some units would have used ML rifles and carbines. Of course Confederate cavalry used ML's extensively, including rifles. If I remember right the 62nd VA Mounted Infantry even used rifle-muskets, at least a part did. I may be mis-remembering there, if I am, somebody correct me.
And by the way, I've seen what Schuyler, Hartley and Graham and some of the other dealers paid for surplus guns and ammo, and it just about makes me sick. What makes me sicker is that most of those guns that went to Europe stayed there. :cursing:
