Not sure if I should offer congratulations or condolences, maybe both. Hope you have a standing bench rest and maybe an assistant to lean against you when you touch that thing off. I wish I could find the article again about the guy who would regulate the big doubles for Holland & Holland. He was still shooting the 577's and 600's at 80 years old. I would have a tough time telling when it was on at all as I would be done by three shots if that many.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
