We need to stop suggesting LEE dies - I'm fairly certain Lee doesn't currently make 41Lc dies (never did?) and LEE certainly don't make 8mm Lebel Revolver dies and never did.
LEE DOES NOT MAKE DIES FOR THE LEBEL REVOLVER - They only make dies for the 8MM LEBEL RIFLE. The revolver cartridges are not the same as the rifle cartridge. Be careful, you wouldn't be the first person to order the rifle dies by mistake.
The 8mm Lebel is a French rifle cartridge, the world's 1st military cartridge designed for smokeless powder. It is also commonly known as
8mmx51 Lebel.
The 8mm French Service Revolver or
8mm French Ordinance Revolver is commonly (but incorrectly) known as
8mm Lebel Revolver, and occasionally also listed as
8mmx27R.
There are pictures of the cartridges here:

The best 8mmLR dies I've used are Hornady. The Hornady die set has a tapered expander that works well for expanding 32-20 brass, the RCBS and C-H not quite as good.
http://www.midwayusa.com/product/59...de-new-dimension-3-die-set-8mm-lebel-revolver Hornady only makes a run of these dies every 1-2 years. Watch ebay. I got mine on ebay for $80 shipped.
41LC dies are easier to find, Redding and RCBS.
https://www.buffaloarms.com/Buffalo_Arms_Company_it-163133.aspx?CAT=4044 for about $100 plus shipping. I got my 41LC dies on the EE here for $50 shipped.
Cost? the dies are a one time buy and no great consideration - people who buy and shoot obsolete and antique firearms aren't doing it because they want economical shooting. If you want cheap dies and components you should have bought a 30-06 and a 38 special. When you buy a $1000 - $5000 antique revolver, spending $100 or $150 on dies is nothing. And the other components will cost more as well.
Plan on spending well over a $1/case for 41 LC brass. Bullets are available if you look. Cheapest is to cast them yourself but 41LC molds are harder to find and can be expensive. The popular Ideal HB mold hasn't been made for 40 years and sells for over $300 - $400 on ebay, when they show up.
8MM LR bullets are also available and occasionally there is some Fiocchoi brass around, but it is rare. Most people make this brass from 32-20 brass, which is readily available, see my earlier note on Hornady dies. The best 32-20 brass to use is Winchester and Starline, with preference to the Starline. Avoid Remington. Expanding the brass is simple, but heavy trimming is needed - over a 1/4" - so a hand trimmer is hardly practical. If you are going to use 32-20 brass, get a shellholder for 32-20, NOT the Hornady 8mmLR shellholder. Yes, there is a difference.
NEITHER the 41LC or 8mmLR is a great choice for a new reloader to learn on and start out with, but it is do-able. If you want to shoot these old guns, reloading is going to be more expensive than the regular run-of-the-mill stuff, but if you were only worried about cost you wouldn't be dabbling in antiques anyway.
OP: If you posted your location in your profile you might find someone that would be willing to give you hand with loading. Being shy and anonymous doesn't work when you're asking for favours.
