Check my calculations for me. I have a SS with 1/4" at 100 yards per click on the elevation turret. My ballistics calculator says my .223 round will drop approx. 52" at 500 yards when my round is sighted in at 100 yards . At 500 yards each click should raise the point of impact 1.25 inches. So if I dial in 41 "clicks" I should be pretty close at 500 yards. Where am I going wrong?

Sounds right.

However, have you chronographed your particular load? are you aking into consideration elevation, temperature, humidity, etc?

Typically calculating it like this will get you into the ballpark.  To be right now you have to shoot the gun while noting the POI and the scope adjustment.

No chronograph, using Black Hills published muzzle velocity. I am using a 24" barrel so I hope my actual MV is close. Did plug in altitude, temperature, scope height above bore center and bullet specs. Just hoping to get "on paper" and do fine adjustments from there.

Sounds like you are on the right track.  Some barrels are faster or slower, but you should be able to get on paper.
