Bought a new rifle

[Rmac58]

Nice rifle, once you're sure it's good to shoot, extend the bayonet, may be more accurate.
If you get the chance, shoot it near dusk, it has a bright flash, and nearby leaves will rustle.
I also have an M39. Careful with those Mosin Nagant's, they have a tendency to breed! See the baby?

EDIT: Yeah, the old ammo is cheap, and the rifle needs to be cleaned after, but not a big deal, you should do that anyway. Using Hoppe's #9 works fine. The corrosive gunpowder is the culprit, I understand, not the Berdan (named after the inventor) primer. That is just very difficult to use again, or reload. Far more problematic than Boxer (named after the inventor, again) primed.

Second pic, you can almost detect two dots surrounding the center strike, those are the primers. You need to remove both to reload.

Third pic is of a Boxer primed spent brass, note the single primer, much easier to extract.
