Worth getting a rifle in 7.62x39 anymore?

[bushmaster06]

Russian Brown Bear 7.62x39 subsonic, 196 grain ammo will not cycle the action of my Mini Thirty nor KR-103.
Hornady has a subsonic 7.62x39 that claims it will work in semi-autos but I've not tried it; https://www.hornady.com/ammunition/rifle/7.62x39-255-gr-sub-x-subsonic#!/

I don't recall the Brown Bear or the PPU cycling my KS-47 either.

Well, I ended up getting the Zastava in 7.62x39. If I end up liking the AK platform, I may get another one in 5.56.

If you're interested in a Magpul folding stock I have one in the classifieds.
