Just posting my error for anyone else new here.

I bought a few 50 round boxes of IMI 7.62x51 150gr ammo to break in the barrel on my Savage 10 (20" bbl, 1:10 twist, Insight Heathen Brake). The best group at 50 yards was over 3" with the rifle mounted on sand bags.

I'm not claiming to be a fantastic shooter or anything, but I shot a better group from the same distance with my Henry .22LR lever action without sandbags.

I'm guessing this is meant to be MG ammo, or something. Or it is just the wrong ammo to use in a bolt gun.

FWIW, the flap on the box is stamped 10-031-8099-1.

I have some 175gr SMK from Sig Sauer on order to try next.

You might have to buy and try about 6 - 10 or more boxes and find out what round it likes best.
Some barrels are really finicky.

Hope I get lucky with the 175gr SMKs then. In today's ammo market it is not only expensive to try a bunch of rounds, it is hard to find them. LOL
