^^^^^What tacfoley said !^^^^^^^^^^^^^^^^^^
--But - you can do without the box and black powder licence and shoot BP substitutes, such as Pyrodex - but then you will be a frilly-pantied gurly-weed, and no respectable gentleman will acknowledge you !
- Also, if you like the Remington copies, and want to shoot in Western-style competition, don't buy the model with the target sights. I did - love the gun, but was assaulted by a horde of "rivet-counters", who said they would accept the stainless steel model I had (I don't like rusty guns), as nickel guns looked the same and they did have those in 1858, but under no circumstances would they allow me to shoot in their competitions, as the target sights were not 'period appropriate'. No loss to me, as it isn't really my thing, but worth knowing.
Regarding the glass vials for storage - if you prefer something a little less breakable, the tapered centrifuge vials come in plastic, with a natty storage box available. I use 21grains of BP in my .44 for 25 metre shooting and it just fits perfectly in a 1.5ml vial, dirt cheap from fleabay.
Otherwise, welcome to the Dark Side - as they say "we have cookies" (and fun).
