That Russian ammo may or may not be suitable for an M1 Garand, I don't know. The Garand's design make it sensitive to excessive gas port pressures, excessive gas port pressure, besides beating the action unnecessarily, can cause a bent operating rod, which you don't want. The Garand was designed around powders like IMR 4895 and IMR 4064 and in particular, slower powders will have higher port pressures. I have shot Garands in High Power competition until I switched to the AR platform in the mid 2000s, and I had good results with IMR 4064 and 168 gr. and 175 gr. Sierra Match Kings.
