I am wanting to enter data in ChairGun For the BSA scope noted in post title that is going on my new Cricket.
Can someone experienced with the latest version of ChairGun point out which scope reticle I need to chose that will closely match my scope.
Thanks

I would use 20X 1/2 Mil-Dot IR reticle in ChairGun, and select 10X for the magnification (instead of the default 20X), regardless of where you have your scope magnification set.... That will give you enough MilDots to take advantage of the reticle in the scope.... Please note that the short lines on the reticle in your scope are NOT 1/2 MilDots, they are the odd numbered Mils, and the long lines are the even numbered ones.... I know because I have that scope, and checked it out on a measured target at a measured range to confirm.... Yes, that means there are 18 MilDots available for holdover at up to about 9X, which is when the post is at the bottom of the field of view.... at 14X, you can see the 5th long line down, with gives you 10 MilDots of holdover available....
When you set up ChairGun as I suggest, the lines that would normally represent the 1/2 MilDot locations are the short lines in your scope, and the lines that would normally represent the full MilDot locations are the long lines in your scope.... After the 10th line down, you will note that the lines in ChairGun are twice as far apart, so they represent only the long lines in your scope.... That reticle in ChairGun stops at what will be 16 MilDots down in your scope.... Sighted at 100 yards, with a BC of 0.05 at 950 fps.... 16 dots down should be good for about 250 yards.... :o
