Wanting to Start Reloading my 7.62x54R rounds. - Page 2

Roll the clock back 30 years. There was no surplus 7.62x 54 ammo to be found. Norma was the only seller of this ammo and back then it was around $20 a box....if you could find it.
I had a Westinghouse Mosin and was able to shoot it with Norma brass and reloads. My bore slugged out at 311.

Since then and with many Mosins imported these days, I have slugged many bores and agree, they run the range from .308 to .313. I have heard others find bores larger than .313.

FYI, if it hasn't been explained yet....

7.62x53R brass is all you're going to find, commercially, for 7.62x54R. It's the same thing, with a 1mm shorter neck.
Everything I have seen, commercially produced, uses 7.62x53R dimensions, even if it is sold as "7.62x54R". So, don't freak out if you run across the substitution; and do keep that difference in mind while checking case length and/or setting seating depth for crimp grooves/cannelures.

It's even worse than the internet would lead you to believe.
