Windage Chart - Freedom - 04-18-2013
I think I know how to read this chart...but not sure??? Can someone tell me how to read this chart correctly.
Does it even work?? How can it work if there is no place to enter bullet BC

Good friends Kenny Wasserburger with help and input from Jimbo Terry and Bryan Youngberg developed that chart. The instructions are on the back, so if you purchase the thing you'll see on the back side what bullets etc it's for.
Yes it works and works well and even works with bullets other than what the thing was designed around.
One of the better investments a person can make to assist in increasing good hit percentages.

similar charts can be generated if you have a copy of rsi shooting lab.
the big problem is establishing a b.c. for the bullet.
the best way to do it is to chrono the load, then use the velocity and established trajectory tto get a b.c.
only thing is b.c changes quite a bit through the transsonic zone.
they are very helpful charts.
keep safe,

Thanks Guys...I wanted to buy it, but since Shiloh feels it is perfectly ok to "Jack" you for $16.05 in shipping for every little thing....This is a little disapointing, I just don't understand how they can feel justified in treating people like that? I live close by, so I make it into BigTimber a few times a year. I'll have to see about picking one up next time I'm there.
The details on the item are quite vague, so I sure didn't want to buy a photocopy or a wallet card for $41.05 just to find it didn't apply to my gun/load.
