I have a Redfield Accu-Ranger Sabot ML 3-9X42 on my CVA Optima. It is not a high dollar scope but it seems to do the job and has the Leupold warranty. As far as bullets, I use what is cheap and shoots well, usually something around 250 gr. Plain lead HP's such as TC Cheap Shot in sabots are fairly inexpensive. TC Sure Fire are jacketed HP 230 gr. bullets in sabots that seem to shoot decent. Both of these should do OK as deer ammo.
