[QUOTE="rufous, post: 18722, member: 122"] Darryl, the Sierra would have 100 foot-lbs more energy at 600 yards. Not really significant (2040 versus 1940). I do not understand what you are saying regarding the clicks up. First you say with the 220 zeroed at 250 yards and then you say up 25 clicks from 100 yard zero. I zero at 250 and then it would be up 27 clicks to rezero at 500 yards (elevation 900 feet). To rezero at 600 I would need 40 clicks up according to my program. I am using bc of 0.655. Also I do not see how the Burris rings and inserts would help. The problem is not that I run out of available clicks, but that I run out of hash marks. Thanks for your input but I am not entirely following you. I suppose I could go up 10 clicks and then reset the zero and then go up another 30 clicks to get zeroed at 600 yards. Hopefully I would remember to go down the proper amount to get rezeroed at 250. The scope just fogged up. I do not think I did anything out of the ordinary. They are not supposed to do that, regardless of going from warm to cold environment. I did send it back and they had it returned to me within 1 week. Great service. They replaced the objective lens.
