Thanks grizz,
I have only shot 600 yds at known range but will have to give my GPS a new mission!
I like to dial in for the distance using the ballistic tables and a sheet of freezer paper.
The pic is how i set up my 200 yard target.
I have used Olhlers BEX program in the past but am not able to run it on the new computers as its an old DOS program. I had an old 486 laptop just for gun use but it has since died and so have all the GOOD old dos programs,
Anyway my 140 gr. SST with a .495 BC will be about 16.5" high @200 when zero'ed @500 So i just walk my hit's up on the freezer paper.
Then FFE
