I have a vaquero SS 4 5/8 barrel in 45 colt. When I got the gun I could hit a paper plate at 100 yds 3 out of 5 shots(with witnesses) I had a trigger job done by a gunsmith I consider very competent. It seems that ever since then it shoots about 10-12 in to the right at 25yds. Have you ever heard of anything like this? After reading the smithing forum,I checked everything out ie: timing,cyl end shake,etc. The only thing I've found is the typical undersized throats. Any thoughts????
