I can find absolutely no reason whatever to buy anything other than Remington, Winchester, Federal, Hornady, or other USA ammunition.!!!
I hope you are saying this tongue in cheek. Norma makes some of the best stuff out there but for a premium. I' ve used their brass before and can say its much better made and requires much less trimming and culling than domestic stuff, and lasts longer to boot. If you want to shoot a cartridge that is of foreign origin, such as 6.5x55 or 8x57 and want factory loads that are loaded anywhere near the cartridge' s potential, don' t even bother looking at domestic made stuff.
