i like his talk. ive actually called sierra and ask if they were planning on some new bullets for the 7.62x39 and the engineer acted like i was crazy. the biggest problem with the 7.62x39 is the lack of bulley sellections. the blackout has all kinds of choices using a 30 cal. i have a soft spot for the 7.62x39, i dont think its potental has been fully explored, but the blackout does fill the void there IMO. the versability of just changing the barrel is its greatest appeal to me.
