RA 17 should be Rock Island Arsenal, 1917 mfg. .30-40 Krag (.30 US, .30 US Govt, .30 USA). Don't know about the "R" stamp on the primer.

US service rifle cartridge from 1892 to 1903, replaced by the .30-03 Springfield, which was replaced in 1906 with the .30-06.

Apparently military arsenals produced some Krag ammo at least through WW I, if I am right and it is Rock Island. I've seen and shot old Remington ammo, marked .30 USA (commercial ammo), and with that headstamp, its not Remington commerical ammo.
