Neither of those videos had anything to do with accuracy. They were about velocity and the deviation thereof. With that, and that Labradar, i thought he laid that out pretty well.
He has other videos on accuracy.
I'll give Wolf a try.
My mindset going in to the 7.62x39 was that I didn't want to handload for it. Rather, take advantage of low cost ammo.
Who knows, I might end up handloading a bit too.
Shane, if you decide to load up some of your own, Starline has been offering 7.62x39 for a few months now.
