If your planning on staying Red Rifle Milsurp you should get:
All the Tula Factory years 1949 to 1955/56 (that's eight rifles). GFL finding a 1949. I'll give my other nut for one. Then have 1 or 2 extra to beat on. Then go over to IZH.
SVT40. (7.62X54R)
Mosin Nangat M38 and M44. (7.62X54R)
Then to keep in the tradition of 7.62X39:
Egyptian Rashid (the cousin to the SKS)
VZ 52/57.
Then when you have all of those, you jump into the 20th century to:
CZ-858
You are now officially a Red Rifle Commie Gun Nut (an extension of a core Gun Nut)
AHHH that's better I need to go smoke now.
