How about some pix?
If I had to choose only one of those, I would probably lean towards the 1886, but they are all really fascinating. Not to be argumentive, but I have a different viewpoint on shooting those rifles and reloading ammo for them. If those rifles were as- new-in-box, then yes, shooting them at all would reduce their value. More likely, they may have been used substantially. If that's the case, then no amount of normal shooting that you might do is likely to affect their value at all. Keeping in mind that the1886 is a true black-powder vintage rifle, you don't try to make a magnum out of it with maximum smokeless loads; you can wreck it, ya know......
About reloading bringing you grief: There are the fellows that prefer their reloading to be a high volume affair with some degree of automation, turret presses with umpty-nine die stations and ZERO PROBLEMS. They probably load for perhaps 45 auto and 5.56 NATO, but it's very unlikely that they will load for 44-40 Winchester, because it will bring them grief. Why would anybody even have a 44WCF that's such a PITA to reload for when they could simply have a 44 Special or 44 magnum that's sooooo much easier, right? Well, ask the guys that love their 44-40's and you are likely to find a very different kind of reloader. This fellow likely uses a single-stage press and does most everything by hand. He is not concerned about churning out 2 or 3 thousand rounds for an AR or whatever. But putting together a couple of hundred rounds for a vintage, perhaps obsolete firearm? Why, that's just his game. Where there's a will, he finds a way. And he probably gets more enjoyment per round than the previous fellow. So there ya go. You maybe could have some decent wall-hangers. But if it were me, that 1886 would be going Deer hunting ASAP.
