^^^that is awesome!



Manitou, could you explain what twist 1/666 t means...i only know of 1/12, 1/9 etc?

mayor barrel makers will make any twist you like ie;bartlien,kreiger etc. On my 47h barrel 3 7 twist and this .666 twist bartlein to shoot 90gr bergers min twist is 1/7 berger recomends 1/.65 for there 90gr vld bullets. The 80.5 gr bergers shoot better in a 1/7 twist than the 1/8 twist
