He said plinking/targets/spinners and squirrels... Knowing Coolbrz0 as I do from this forum, I don't read "plinking/targets/spinners and squirrels" to mean benchrest or NRA Smallbore competition...

The advantage of turning down to 25yrds on a 10yrd shot instead of a 100yrd setting seems really close, but it doesn't even cut the potential parallax error in half.

Maximum parallax error in inches is calculated: 0.5 * D * Abs(R-S) / S / 25.4

D = diameter of objective in mm
R = range of target
S = range of parallax free setting

A 40mm objective shooting 10yrds, set at 100yrds is 0.71" error. Set at 25yrds is still 0.47". Both miss the Asprin, or the tiny dot... Getting 75yrds closer in setting only cuts off 30% of the potential error - AND leaves almost 5MOA of miss...
