Use a rifle scope with the 218 Bee. The best value scopes are 3X9s, get an AO if you can. I use a rifle scope on all my Contenders (I have 4 centerfires). The Hornet, 32-20 and .221 are no problem, the 6.8 SPC is a little stout but I hold it down on the bag and make sure I don't get too close. The Bee is perfect for a rifle scope.
Thanx, Russ
P.S. Pistol scopes are a pain, the field of view is small, it's hard to find the target and my arms never seem to be the right length.
