center of scope to bore exbal question
What i am doing now seems to work, but a friend and I are doing this a little different so i wanted to hear how you all are doing this. do you measure the distance from center of bore to center of scope to input into exbal from:
1) near the bolt, or
2) at the front of the scope
with a slanted base the two measurements would be slightly different ( i am thinking) but please correct if wrong.
thanks alot guys.
