It's Friday, so let us suspend reality. Let's pretend I have money to burn and I want a Martini-Henry rifle.
As we're all painfully aware we need pre-authority to possess Section 1 toys, so one does find it is best to think about all the options that are open. Though I believe MHs are Section 58 (perhaps incorrectly), until you want to shoot them.
Knowers of the know, please teach me in the ways of Martini-Henry.
1) I know they're around, and I've seen some of the prices about, but what ones should I look for and which ones should I avoid? I've been told MkIVs are good'uns.
2) Is reloading for them a pig?
a) Are the dies and brass readily available?
b) As the bullets will be paper patched, do you need special, magical bullet paper for the reloading?
As The patch will take up some of the windage I assume the bullet will need to be undersized; does this warrant a custom mould, or is it easier than I imagine to obtain .45" bullets which'll be suitable for shooting in the Martini?
c) Do you need a special press for the cartridge as they'll rather large, or will my standard Lee O-frame press work?
3) Does anyone load black powder substitute in these with any success, or are these beasts only happy with true black powder?
If anyone would like to throw in some interesting info on the Martini that'd be grand. Help a young, eager young'un out.

Thanks for the helps, chap and chapesses.
