X3 on the surplus ammo. Shoots great, and clean up isn't a problem with a Nagant. I just give it a thorough going over with good with good ole #9, rinse, and repeat as they say, and oil the bore well. No corrosion signs what so ever!
Wish I would have bought a bunch more when it was probably much cheaper than now.
