To start with, realize that using an under sized bullet always means that proper neck tension can be a problem (particularly with an autoloader). There are however, ways to address that.
Also note that there aint too many .308 bullets which have a crimp-groove and even if they do, the groove may not be in the right place relative to your intended cartridge-AOL....so if having a crimp-groove is a criteria for you, you'll be somewhat limited as to your bullet choices.
All that said;
I know for sure that a .308-125 Nosler Ballistic Tip sitting over a healthy dose of IMR-4227 and a Federal Match Primer worked surprisingly well in the 7.62X39 guns which we tried it in.
On the other end of that mule, a cheap plinking load for a 7.62X39 gun can be worked up using pulled 7.62 NATO-147 FMJBT bullets and H335.
Once again though, it's important do whatever you gotta do to insure proper neck tension.
Hope something here helped.
