Thanks to everyone that posted to help me choose which 642 to get. I ended up getting the non CT model and I've been to the range twice with it. Shot it at 22 and 35 feet with identical results, groups that are high and right. I used 148 LWC and 158 CPRN home rolled along with 100gr Fed Hydrashock and 125 Fed premium HP. They all shoot the same. I had someone else shoot it and he was not grouping so I can't tell if it is me or not. Here is a photo of a target at 35 feet. Do your 642's shoot high and right?
