I would just get a box of the reloadable stuff and keep a hold of the brass for reloading, especially if you know anyone with the equipment or are looking to get into doing it yourself.
I can certainly relate as I am in your same situation too after having just bought an Mosin 91/30 and M44. I saw some surplus ammo at the gun show in Edmonton a month ago going for about $8-$15 for 20 rounds.
Also, the reloadable stuff will at least prolong your rifles since they won't be corrosive as the surplus stuff is.
