Sorry David, I don't have any direct experience. I was so close to buying a Ruger #1 in 7.62x39 a few years back. I did a lot of research on bullets and loads. I'd like to see one of the manufacturers make a premium .311 bullet. About 2 years ago it seems to me that Nosler did a limited run of Accubonds in 311. It'd be nice if they were still available. Sierra doesn't get a lot of love on this forum, but their .311 125 or 150 Pro Hunter would be a good place to start. I might even be inclined to try 125 grain BTs. There was a discussion on here a while back about that bullet, and the consensus is that it is a surprisingly tough bullet. I think MD even commented on its toughness.
