How Often and Under What Circumstances To Check Zero?

im meaning "return" in this case with RTZ in reference to the optic alone
but in a rifle system, both returning and retaining carry equal weight...returning to zero can be a test of the optic itself...
retaining zero requires the mounts and rifle to not throw a wrench into things...mounts cant shift on rails, rails cant loosen/shift (if not integral), rifle cant shift in stock/chassis...none of those are the fault of the optic
you can test optic tracking and return to zero on a jig completely separate from the rifle...retaining is a test of the whole system
on a really well mated rifle system you can take anything that indexes apart and put it back to together and the zero will still be good...
barrel off
rings off rail (need to leave the rings on the scope because round scope body is nothing to really index off of)
action out of stock
^^**Disclaimer: i havent seen many components, even the high end ones that can do this right out of the box and just bolted together...some can/will, but not most
reassemble and it should be good to go...if it moves any amount outside of the shooters ability to repeat himself, there is something in that system than can shift if it sees a force hard enough in the right spot...just a matter of time
