Eldorado Cartridge was the upscale (Gold Box) PMC ammo that was factory loaded with Barnes X Bullets about 10 years (+/-) ago. I shot a lot of them through both 30-06 & .270 WIN rifles. I have never reloaded the cases, but did save them for future use. I have loaded a lot of PMC revolver brass and it performs on par with the RP, WW, & FC brass I have also used. Odessa
