Yes depends on caliber of ammo and load: If all ammo flew straight without the typical parabolic curve then everything would be easier in perfect wind/temp conditions. Most hunters IMO will get on paper and then make sure they are as close as possible for POA/POI at their long distance Zero or intended range for hunting. A 25 yard hunter does not have the same considerations as someone whose shots are usually taken at 300+ yards.
Some with higher caliber rifles want various ranges with little or no hold over; some chose 100/200/300/etc etc out to 1000 yards for POI.
Irons, Red Dots, and type of scope coupled the shooters capabilities all factor into the equation. Not everyone owns a Sheppard scope....I think this and the other thread (one shot zero) should have been about the Sheppard scope and how those who have one are satisfied with their one shot zero. What ever works for the individual comfort zone and equipment in use.
http://rimfirecentral.com/forums/showthread.php?t=56146&highlight=trajectory which is a recommended .22 sight in and zero which does not equate to a 223/5.56 or any other caliber for a rifle. When barrel length, ammo type and load with individual weapon used bring variables into the equation. Will a scope that is zeroed on my .22 work with a same zero on my 30.06 even if the same height above bore?? Maybe close on windage/azimuth but elevation will change drastically at various ranges; obviously.
I personally have some decent equipment and mounts on my rifles but if the scope is removed for any reason then I always re-check zero if reinstalled back on same rifle. The only reason I say this is because the smallest difference in mounting can make a detrimental change of POI at longer ranges.
I hate to remove a night scope because it requires a re-zero after sun set. Can I take it off and then put it back on; yes I can and sometimes it is still right on for my intended uses. But if I am using the night scope for game at 100 yards my expectations are for my POIs to be within a 2" square with my hunting ammo. Not that great but good enough for my usages.
Again it really comes down to range distance and individual. Some are very happy if they can hit a 12" steel plate at 300 yards and others are disgusted unless they are shooting less than tennis ball groups at that range. What ever method you use and are comfortable with then use it and be happy. If your POI at what ever range you are shooting at is consistently on target then sounds like to me you are zeroed. I usually shoot with a 223/5.56 at 27 yards and adjust scope for POI. Sometime depending on how far I had to adjust the cross hairs I will take 3 to 6 shots but I am very picky with shot placement. I then pick target at the range/distance for the irons, Red Dot, Or scope and check POI which usually requires only a small elevation change. Maybe redundant but like I said before, I do not like to do my part and have the bullet miss my target because of equipment. 6 to 10 for me but if I need more then "oh well, so be it".
