Bought NIB 1:13 twist for 600 YD competition. Desperate for guidance: cannot get to group---very frustrated.
This rifle supposed to be 155g shooter.
have tried Varget up to 46.0g behind 155g B155VLD, B155Hybrid, Lapua 155 scenars, Sierra 155 HPBT, Sierra 155 Palmas--------trying to find THE bullet----no conclusive results. Today shot B155VLD at +.002 into lands, at lands, -.002, -.004,-.006, -.008 with 46.0g Varget-----no groups? Had thought 46.0g Varget was the sweet spot??? Chronos at 3050 with low ES.
have also tried Winchester 760 with 47.0g---various bullets.
seemed like some success with 150s.

still looking for a direction.

if anyone has experience with this specific rifle, please help.
