So I just nock tuned the arrows I'm shooting (Bloodsport Hunter .004 straightness). Two were hitting right in the middle and two were hitting to the right. Nock tuning brought the two hitting right to group much better with the other two. As I don't have much experience with different arrows, would you say it's "normal" to need nock tuning regardless of the arrow brand and model? I guess I'm just curious if what I experienced was a normal part of arrows and archery or if it's more so from these specific arrows? Just trying to learn.
