Need some infor on a loaded round I have

[skeet]

Have an old loaded round that I need to find out about. The headstamp is FYA on the top..HP on the bottom. dated 19on one side 28 on the other so I assume 1928. Bullet is crimped or actually staked..no on second look crimped and the bullet is cupro nickle jacketed FMJ. Loaded round weighs 369 gr exactly on my Dillon D terminator.. Case dimensions as cloase as I can measure a loaded round 2.9545 OAL Case length 2.1035 Rim Dia..0473 case diameter just above the rim .464 Length to base of shoulder 1.775 to the base of the neck 1.867 Diameter of the case just below the shoulder is .428 Oh and the bullet size is .3085 Nominal 30 cal. It looks like a 308 Winchester but 1928?? Any help would be appreciated..
