I picked up a nice lot of ammo from a forum member this weekend.
Czech silver tip BXN-55
http://7.62x54r.net/MosinID/MosinAmmo011.htm
and what looks like Bulgarian yellow tip 10-55
http://7.62x54r.net/MosinID/MosinAmmo016.htm
All very clean and serviceable. The Bulgarian is brass so I can make some custom loads!
