Since it's pretty close to .300 Savage, I think you're pretty well off with a soft-point, 150gr offering. If you don't reload, I'd advise to go with Remington Factory. They've done us very well in .300 Savage over the years.

As for military surplus 7.62 NATO ammo, you need expansion and the NATO Full Metal Jackets won't do it.
