Thanks! I found it. I'll ask what he knows but he said in the post that he got it from a friend who's cousin is a gunsmith who rebarreled and chambered it when he was in school. Maybe I can contact his friend's cousin.
I also found a thread on another forum by a guy who was converting an sks...
How much work/ money would it take? Is the 6.5 Grendel really a necked down 7.62x39? I know its based on the .220 Russian and that is based on the 7.62x39 but are the case dimensions close enough rebarrel and use the same action? Just curious really.
I searched "7.62x39 wildcat" and a thread here came up. Just think a 6x39 would perform better. I like the knowlege and respect the responders showed the person who asked . That's important to me because I might ask a newb question and don't want to be treated like an idiot. :)
