I love it. (I use the rz800). I have found the calculators to be just a few inches off at 600 yards. I zero at 200, check the 300 and 600 and go from there. Put two rounds in a 6” bullseye at 600 yards the other day. Calculator said put my zoom on 11.5. I found my scope is best calibrated for that range at 11.2 zoom. Made a note and everything in between 300 and 600 should be pretty close. Shooting a 6.5 saum, built on a model 7 action.
