Anyone want to comment on the practical difference between the 300BO with its best bullets, and the 7.62x39, with 123gr softpoints?
Since I actually do have the parts to assemble a PSA in the cartridge.
Much better bullets available for the 300, otherwise the ballistics are so similar it doesn't matter. The bullet selection is a big deal though, don't overlook that.
If you're putting it in an AR15, the 300 is far easier and uses all common parts.
