I am loading 7.62x54R with a Lee loader and can spin the boolits when they are seated in the case. I am using twice fired PPU brass and the Lee 312-185-1R mold. Boolits are dropping at .312-.313 and lubed with Alox. Even after I crimp the boolits they still feel a little loose. After sizing, inside of case necks are measuring(caliper) .309-.310.
Forgot to mention I am not using a gas check on these.
Not hunting with these loads just plinking.
Any ideas or suggestions would be appreciated.
Thanks!
