Below is a shot of a target I shot earlier this week. Shot with a mostly stock Savage 10fcp with IOR scope (has factory HS stock and has had barrel shortened to 20" and threaded for suppressor). Did not have suppressor attached. Was shot at 100 yards from a bench. Gun is zeroed for Federal Gold Medal Match ammo and the top target was 10 shots with the Federal ammo. You can see its all right on the bull and measures right at 1 inch. Bottom target was shot with some Prvi Match ammo using the same 168 gr. bthp bullet the Federal uses. You can see point of aim moved dramatically and they did not group nearly as well as the Federal. It measures right about 2 inches. These were shot within minutes of shooting the first target and this was duplicated several times during the day, proving the Federal to be perfectly on point of aim and consistently measuring an inch or less, while the Prvi was consistently high and grouped between 2 and 2 1/2 inches. So even though its "match" ammo and using the same bullet, there is an obvious difference between the two. I can live with the point of aim shift, but it doesnt really group either so its definitely inferior in its consistency of manufacture, or simply my gun doesnt like it. Though I do get similar results with my FNAR semi-auto .308 as well. So the lesson is that quality ammo does make a difference and also that you need to zero your gun with whatever you plan on using and make sure your gun likes it. If I were to assume that the Prvi zeroed the same as the Federal, it would be quite off as the distances increased.
