She normally shoots a 30" Ljutic Mono very well. Bought her a K-80 step rib trap with a 30" barrel, and he can't hit an angle target with it. Straightaways hit about 80% of the time. Gun fits,and on the pattern board at 13 yards the point of impact is EXACTLY the same as the Ljutic. She shot a 13 with the K-80, picked up the Ljutic and shot a 24. K-80 may be a little heavier but not much. Can it be lock time or something like that? GaryL.
