I would like to hear some thoughts on why I'm having difficulty getting my windage holds figured out so here's a little background for ya. I'm shooting a factory A-Bolt 300wsm. with a factory 2lb. trigger and a muzzle brake. The rifle shoots great shooting factory Fusion ammo 165grn. When I say great I mean .5moa at 530yds. the other day and many other days when I'm shooting well. I have had great luck with this setup and it has proven to be very consistant. The elevation holds are all extremely consistant with what the ballistic program says but the windage holds are off quite a bit? I have created my own windage holds through real life shooting tests and they have proven to be consistant. SO WHY COMPLAIN RIGHT! My question is why are my holds so different than the calculator? On the calculator it calls for 1.6moa hold for a full value 5mph wind. In my tests I have found that I have to hold 2.5moa. This is just 1 example but I have found my tests to be consistant as I said. All the info in the program is accurate so what gives? My only guess is that I have a lack of understanding on just how much wind there actually is in my bullets path. I am using a wind meter that I have tested against others and it reads true. Any thoughts???
