I got a 3 groove Pac-Nor 260 that shoots in the .3's at 100yds (5shots) and consistently less than half MOA at longer ranges.
photo shows four less than 1.5" at 400yds. and yes one flyer but that was me i called it when it broke.
PAC-NOR is good JU-JU [img]/ubbthreads/images/graemlins/grin.gif[/img]
BTW pics not meant to discredit precision capability of Pac-Nor barrels, i'm sure they will shoot far better than i can.
