What scope are you using? We have tried several scopes, I have given up on finding a quailty scope under, $ 450.00, we are trying a pair of Weaver T-36's right now, very good scopes, but concernes how the 36 fix power will be in heavy mirage. I also have Leupold VX-3 6.5-20 that works really well, would like to have abit more magnification, the other scope we have we found we like very much is the Sightron SIII 8.5-32 power, it has great glass in it also.
