I only shot two sabertooths out of my Optima both shots hit about 1inch low at 50 yds,that was to be expected going from a 245gr Powerbelt to a 300gr sabertooth.But I didn't want to start screwing around with my scope beceause the M/L season starts monday and my gun with the 245gr Powerbelt and 100gr of T7pellets shoots great,I will try more after the season.
