Remington 8mm Ammo is prevalent. I like Remington Brass for my Military Handloads because of its soft Brass. I can turn twenty rounds into 200 when using reduced loads.
Winchester is great ammo, always has been. My Yugo 8mm does not like it, but, still good ammo.
Federal 8mm works great in my Mauser. Brass is great too for reloading. A bit pricier than Remington ammo but worth it.
My favorite ammo for the Yugo 48 Mauser is Prvi Partisan. Brass is hard and good for reloading full-house loads – not good for reduced loads as it allows for blowback when reduced pressures do not allow the brass to “Seal” in the chamber. Prvi Partisan 8mm Mauser ammo is “Sub MOA” in my Yugo – consistently! Click the picture for the Prvi Partisan Ballistics chart. Their numbers are in metric.
Take any round from above or any round combo you want to load and input the data into the Bear Tooth Calculator and you will have your Ballistics Info. Great site and great calculator for the Handloader.
