mine shots 1/4 inch groups,just found that out yesterday,with hornady light mag sp 139 grns,i also instaled the sims barrel de-resonator.ishot right inside some else bullet hole at 130 yards,i could do a little better if i had a multi-x retical instead of the firefly retical,its kind of thick, and it kind of hides behind the crosshairs,the small targets that is...o well its a hunting rifle not a target rifle..i am really pleased with its performance..i was getting little over 1 inch with out the sims resonator...its the a-bolt 7mm-08
