7.62x54R? You got to be kidding, my friend.
Just get an issue of Shotgun News or visit some decent gunshow - this ammo is everywhere.. Average price - $12-14 per 100.
You can get it by mail order very cheap.
I use Sellier & Bellot but there are several others out there.. The S&B is the better quality. I have had some problems with the old surplus stuff (duds)
so picking up a Nagant carbine in 7.62X54 for under $100 ainr gonna be a 'wallhanger' type deal? They make anything in semi-auto? Hey...almost all of my firearms are Russian...do I see a trend?
