The 30 Lugar uses a .309 dia. bullet however some have experienced excellent results using the .308 dia. bullets. None of the major mfg. currently make a 93 gr. FMJ in either 309 or .310. Your best bet is to either try the Hornady 90 gr. .309 XTP or Sierra SportMaster 85 gr. in .308.

Since Fiocchi USA imports the 30 Lugar ammo which has a .309 93 gr. FMJ bullet you may be able to contact them
