All the lads ara bang on
But don't foget !
Chair gun need the pellet drop
Fps
Weight of pellet
Zero range
When you've got these what ever range you've zeroed in at , fire 3 rounds at that the bull , then move back say 20 yards ,
And shoot another group at the bull again , measure the distance the pellet has dropped from the bull , enter this into chair gun and you will find the program will change thing round slightly , you can then play with the magnification on the program
An d find out the best one for 5yard increments on your scope , belive me this works a treat
