Cold bore zero versus (very) Hot bore zero “test”

[Formidilosus]

I am not sure if this has been asked before but for hunting purposes , would multiple 3 shot cold bore groups be more useful for establishing a zero vs one large hot bore group?

Ehh. It doesn’t really matter that much. Just get 20’ish shots on a single aiming point and go from there.

The best thing for most would be to break and build the position for each shot, for those twenty rounds. The group will be larger, but will center you true cone.
