Just bought my omega about a year ago but it was quick and easy to sight in and find an accurate load for I figured TC sent the 240 gr. mag sabots with the rifle for a reason so I bought a package of them and used two 50 grain pyrodex pellets along with some CCI 209M primers I had on hand, went to the range and impresed the heck out of myself. the omega will shoot 1 to1-1/4 inch 100yd. groups till you get tired of pulling the trigger (or till your shoulder gives out) I havent yet felt the need to do a lot of other load testing but will, if for nothing else for peace of mind and what if?
