Usually just the bags and a bench.That's the easy part .Most people think I'm nuts,But .First I take the scope ( if new in box) go through the entire vertical and horizontal range all the way up and all the way down click to click end to end.I count the clicks from stop to stop and then split the difference.In my mind I think I am exactly in the middle of the adjustment range.Then I mount the base with loc-tite then I use the Wheeler scope leveling device.If sighting in a bolt gun,I put it in the vise .I then put a piece of paper on the wall across the room with a 1/2" dot on it.looking thru the bore I line the hole up with the dot then adjust the scope to center of cross hairs to center of dot.This should get me on the paper at 25 yards.If on paper first shot ,move to 100.3 shot group adjust and then another 3 shot group.oops I forgot a couple of fouling shots.Now is where the fun starts .I am a firm believer in "cold barrel zero" for my hunting guns.I will shoot 1 shot go home .Next day I shoot another shot go home .Takes 3 days to get my "first " 3 shot group.I adjust and repeat as necessary.That way I know that the first shot on that 30 degree morning that I am dead on with a cold gun.Might be a little anal but it works for me.Let the ribbing begin......LOL
