Killer criterion - the repeating mechanism

Yes. Apart from the checks you should make on any rifle that old - Check that all the bits are there! This is not a joke, and not so easy to tell if you have never dismantled one.
Bits that are frequently missing include:
1. The magazine-tube spring.
2. The boss on the breech end of the spring. This is shaped with a step, so that when the last round has been fired, it prevents
3. The loading interlock fork* from moving in from the left, which in its turn prevents the carrier from descending to pick up a non-existent round. In this state, the rifle can only be used as a single-shot rifle.
The parts are dimensioned so that when the last round has been fired, the interlock fork will come up against the step on the boss, thus preventing the boss from being pushed right back onto the carrier tray (causing a snarl-up). If the boss on the end of the spring is missing, the end of the spring will EITHER become tangled up with the interlock fork OR work through until it is tangled with the carrier. Do NOT try to force the action open, unless you are keen on making a new spring. If you have this particular snarl-up, you will have to dismantle the action quite carefully to get it all untangled again. (A collector friend had this problem, and was completely baffled. I am, as in most cases, speaking from experience!)
*I am not sure what the correct term for this item is, but it is to be found on the left side of the mechanism.
If a round is still left in the magazine, the spring pushes it back so far that the front end of the fork can slip behind the rim of the base of the cartridge. The fork is pivoted, and so the back end of the fork moves away from the carrier, permitting the carrier to move down and pick up a round.
If this is all a bit tricky to understand, you have my sympathy. I did not get it at all until I actually had a 71/84 in my hands to play with. Failing that, if you can get a look at an 1886 Kropatschek, which is a rifle with basically the same mechanism, adapted for an 8mm bullet, you will be better able to understand what I am endeavoring to describe.
In short, the spring could be replaced, and the boss could be turned up if you have an original to copy. Don't bother looking for dimensioned drawings - I doubt there are any to be found - you must have an original to copy.
The interlock fork is quite impossible to duplicate unless you have an original. Like the extractor fork on a Martini, the chances of getting it right by cut-and try methods are approximately 5/8 of FA (for UK readers) or zilch (for the rest). For the normal user I would recommend - if the interlock fork is missing, look for a different rifle.
Lack of any of the 3 components described above will prevent the rifle functioning as a repeater. And you have got to have the rifle in your hands to tell! Buying online is a definite no-no in this case, unless the seller warrants that all parts are present and functioning.

Not so. Lee makes economical dies. Cases are available. You just need 0.446 lead bullets in the range 320-500 gn and with Brinell hardness around 10-12. No harder than 15. And load with Swiss No. 4 or 3 (FFg or FFFg). Or send a lot of money to Buffalo Arms - they have ready-loaded ammo, at a price.*
Dear Steve, in the nicest possible way, and with no derogatory intent ... chicken!:D
Go on, have a go!:thup:

*Why not buy a 20-pack to try the rifle out, and then reload, using neck sizing only - you may get the taste for BPCRs?
