.312 bullets can be used for?

[Gatorade]

I have a bunch of 7.62x54r that has corroded and either won't fire or is not safe to fire. This is most commonly for use in Moisin Ganant and Dragunov pattern rifles. The .312 diameter bullet is probably too big for .308 or Blackout reloading so aside from reloading it into 54r cases, what other calibers use a .312 bullet?

I don't have a problem pulling the bullet and setting them aside till I get up the urge to reload for the NDM-86 but I don't have any dies or brass, and I have just under 3K rounds on hand so I am not tight on inventory. Just checking to see what else is out there.
