wow, I can smell a war in here, CALM DOWN!

Well, tomorrow I'm going to Ed's Gun Shop to buy a couple of 3" Slugs, I am going to zero my rifle-sights!

Hey, any tips for zeroing a shotty or is it the same procedure as a rifle.
What would be a good range to zero for slug? 50yd.?

Sorry if I always end a post with questions.
