I still haven't got around to reloading for the x39 yet. I hear the AK can be rough on brass. I have a WASR but it's an underfolder. It's only got cheap steel stuff. Ergos are horrible, but it's not as inaccurate as people would have had me believe. I bet I could do a little better still with a tailored reload, maybe even a cast load.

I do cast a bunch of the Lee "C. E. Harris" design for my 300blk. That was supposedly designed for the x39.
