FMJ for target.
As a general rule, FMJ = targets, JHP & Silvertips HP's for Personal Protection Rounds.
When it comes to the AK & SKS stuff, (7.62 X 39), it's what ever you can get a thousand for, if you can get a thousand at one time now. I was able to get a thousand once that was a blueish match type w/ a 'nipple end' to the bullett. Saw them once.
