If you paid $159 for a genuine Mosin Nagant sniper rifle, you got a cinderella deal! They are often faked up- real ones are going for >$600.
Try www.7.62x54r.net for info. There are also a number of Mosin Nagant groups of Facebook (I’m in two of them) that can help you find out all kinds of info.
There are as many ways of removing cosmoline as there are shooters- I favor low odor mineral spirits and an cut up t-shirt. Be sure to clean the chamber thouroughly- old cosmoline and the laquer on the shells can mix with the heat of firing it, which is the cause of the “sticky bolt” syndrome you’ll be hearing about.

He doesn’t deal in these and wanted to sell it quickly. I was definitely blessed in this deal.
