My grandsons Zastava has just dab of bedding compound by the recoil lug and front screw.

I shot some Hornady Precision Hunter 150 gr. ELD-X loads and they too go into 1-1/4 MOA groups. The rifle has a 1:8 1/2 inch twist. I think that is because the European have always favored heavy bullets in the old classic 7x57mm.
