I'll preface with I've never done long range shooting.
Is 2 out of 10 on target a success in long range? I get that 3000 yards is an insane reach but the number of hits was not impressive (to an untrained eye). Just seemed like guess work go left, go right. No different than when I see some people sighting in rifles at 100 yards.
Also for the record, I would have 0 out of 10 on target.
I'm also impressed with the velocity of the 30-06 at that distance. Who says 30-06 is an old Fudd round?
