Sorry to hear you had such a bad experience with the BSA Tac I have owned a few BSA'S over the years and have never found one that did not do what it said on the box...kill small game at 35yds + ,I have just recently bought a2nd hand BSA Tac of a member and it is absolutely spot on I can get really tight groups at 25-30yds with min.effort on my part, I reckon you were sold a dud as the other one I have a older lightning was zeroed within 5mins at 15 yds
