What 7.62x39 ammo do you use for medium range shooting?

[Caseless]

I always suspected my Unissued Yugo 59/66 has good inherent accuracy. So I installed a Tech sight and thinner front sight blade and tried shooting it prone at the 200 yard range today. It seems the ammo is the limiting factor now. One or two flyer every ten rounds. I was using Wolf 122gr HP.
See picture.
All shots to the left of bull were initial sight-in shots.
