Hello..has anyone purchased or used the Nikon P22 scope with the 150 BDC retical? With Nikon's balistic program, you can custom make a picture with your favorite .22 ammo, calculating and showing the hold overs? This scope runs about $150.00. I know it is only 7 power, but I competed with Lyman 8 power scopes out to 100 yards before with no problem. Any thoughts?
