I've done extensive reloading for 7.62X54R! My full house load is using .311 174gr Sierra Match Kings (TradeEx) with Varget and WLR.
These next two are the same load at 100 yds.
I think this was with Lapua Brass obtained from Prophet River however I've had similar results with PPU brass from Tradex and S&B brass from factory softpoints I bought before I was into reloading. My testing revealed neck sizing was much more accurate so I use a Lee 7.62X55 SWIS collet die to neck size.
I ran a ladder test with my particular Mosin which has a 24" cut / crowned barrel slugged at .311 and found a node at 44.3 gr Varget and approx 2500 fps.

I was able to get much tighter groups however at a more stout charge seen above of 47.3 gr Varget.
For more affordable shooting and fire forming brass I have developed a number of loads for cast bullets by almost every LEE mold that can work with the Mosin. I'm currently working up a load for the Lyman 314299 mold I was able to get from Budget Shooter Supply. Mine casts my pewter sweetened WW alloy at .312 and 206 gr with a gas check.
H4895 is a great powder for cast at higher velocities if your alloy and lube can take em. Most of my reduced loads are very accurate with UNIQUE powder in the 13.5-15 gr range. According to quickload software you want to watch for pressure signs if you're going over 13.5 gr UNIQUE with a 150-200 gr cast bullet.
I haven't used BLc(2) but wanted to give it a try because it's a ball powder is it not? My Lee perfect powder measure works great with ball powders and can almost eliminate the trickling up to charge all together.
I have loads for PPU 150 gr SP and FMJ's as well if you're looking at those bullets. They can be bought cheap from Budget Shooter Supply.
