How would you rate this ammo?

I rate 7.62x39mm ammo into three accuracy groups. But as with all things gun related some guns just won't group with some ammo worth a hoot. One rifle might allow one kind of ammo to move up a group while another rifle might move one type of ammo down a group.

Best
Handloads with .311" bullets
Lapua
Chinese steel core

Good
Handloads with .310" bullets
Chinese lead core
S&B
Winchester
New Remington(.310" bullets)
Russian HP

Poor
Handloads with .308" bullets
Old Remington(.308" bullets)
Russian FMJ

The Chinese ammo you asked about would fall into the good group as it is lead core.
