Checked the theory I had with my blaser R8:
1 Scope (Zeiss 6X24- 56), 1 Moderator (Hardy)
2 Barrels .308 & .243
Turrets Zeroed and locked for the .308 with windage 2 clicks to R
Changed barrel to .243, 9 Clicks up and 2 Clicks L on windage = Bang on Zero .243
Repeated swapping barrels with the same scope about 3 times each, bang on Zero every time!
2 Calibers 1 Set up, which ever you fancy that day.
.308 back on, 200 meter dialed in with BT strips on the Zeiss = hit the inch red circle!
