I have to install some eotech's on the mossberg 500 tac series shotgun. Ultimately they will be deployed with 00 buck and some LTL type rounds so my thinking was to zero the weapon @25yds with slug rounds which I think would give the best poa/poi across the board. Our expertise is with pistols and rifles and limited with shotguns, particularly ones that would be carrying an eotech's. does anyone see any problem with the above methodology? Thanks in advance.
