I have a CZ in 204 Ruger I use for varnmit hunting. It has a Leupold Vari-XIII 6.5x20 scope on it now. I need to know if sending this scope back to Leup. for a 204 calibrated recticle and the turrents is worth the cost? Or am I better off just getting a newer scope with turrents and the varnmit rect.? My wife gave me this scope in the 1980s for Christmas so it an older scope with the fine X-hairs.
