New project? a grendel-cousin?

[grayfox]

So, guys. Cabin fever is setting in. I have loaded rounds, cleaned barrels... fixed a buttstock pad... thinking I need a new small-cal project... maybe a 7.62x39 bolt project? Looking for any good advice/comments/suggestions. I did try a ruger 300 BO but didn't really care for the powders it used. Shot fine, just, well, idk...
So maybe a 7.62-ey? or back into the BO realm? bolt-actions only for now.
