OK, so now, if I understand this correctly, the left to right movement of the group center is immaterial. We're only concerned about the vertical position of the group in reference to the POA?
But now my question is why do some rifles exhibit impact substantial left to right movement in addition to above and below POA as charge weight changes.
I'm trying to understand this and get as much info as possible. I have a 6.5 CM on the way in the form of a Begara b-14 HMR. I want to get a load developed to shoot out to about 600 or 700 yards.
Trying to watch these videos after reading Newberry's method its hard to believe that so many guys are hung up on group size! As soon as I hear them say that that is their node I have to turn them off.
