Reviving the Mosin-Nagant discussion...where did you guys that have them get them?
I saw this as I was goofing off online today -

Surplus from Ukraine so I am thinking luck of the draw finish-wise, but from the comments it appears they all go "bang".
And there is some Hornady & Prvi Patizan bulk cases in 7.62x54 to be had.
I got mine several years ago, a M44 carbine from Classic Arms and a Finnish M39 from some dealer on Gunbroker. I would absolutely get one if you have the chance, they're good solid rifles.
Get yourself a spam can of ammo too. If you've never shot corrosive ammo before, just be sure to thoroughly clean the bore with a water based solvent before your normal cleaning. That's all there is to it.
ETA - I saw a few reviews at that link where people were complaining about the "toxic gel", i.e. cosmoline. It's like, what did they expect?
If you get one, disregard most of the crap you'll read about cleaning the cosmoline with solvents. The most effective way to remove it is with moderate heat. Completely disassemble the rifle, and wrap the wood parts tightly in paper towels. Set your oven to its lowest temperature (usually 150 or 175) and put the parts in there. You will probably have to prop the oven door open, and can use a towel to cover the gap and keep heat in. After about 20-30 minutes most of the cosmoline will have seeped out of the wood and been soaked up by the paper towels. You might need to repeat this a time or two with fresh paper towels before it stops seeping out. Cosmoline melts at 130 degrees, so it's pretty easy to get it out with moderate heat. This is much gentler on the wood than using solvents.
The metal parts are much easier. The small ones can be put in a pot of boiling water for a few minutes, and the larger parts like the barrel/receiver can be hosed down with degreaser. Once you're down to clean metal and wood, just clean it like you would any rifle. I do recommend oiling the stock with something once all the cosmoline is out. I use Howard Feed-N-Wax. It's a beeswax and orange oil product that you wipe on, let soak in for 20-30 minutes, then buff off with clean towels. Great for wood.
