Ok, so I put the rifle to the following test:
I loaded it with VV N140 Powder and Berger BT Target 105 gr bullets. I was shooting between noon and 1 p.m., so the mirage was massive. I am expecting that at nationals next month, so I decided to train during 11.00-14.00 window, so I could challenge mirage every time.
Charge weights for this batch were provided in 0.3 increments, starting with 28.5 gr up to 29.7 gr. I was leveling the rifle, squizing the trigger carefully.
The problem I see is the buttstock- it's MDT SCS stock and it's simply to short. I cannot get full clear view in a natural way behind the gun. I am adjusting my posture every single time, so there is zero repeatability in it. I cannot move the scope mount forward- the scope is mounted at the end of the rail.
Each group is a 5-shot group.
