You should buy this case of Portuguese 8mm. Most of what I've seen is dated in the 70's and is very clean and accurate. Noncorrosive, but berdan primed. In my four 98's, it is better ammo than the Romanian or the 50's Yugo. I can't make a comparison to the 70's Yugo as I havn't shot any of that. I'd certainly buy more of the Portuguese if I could find some. Regards.
