The Hick's unit certainly stopped the wandering zero on my No.1A 7X57. So far, I'm impressed. In addition, group size has shrunk a little. This is with only 1/4 turn of of the screw after contact with the barrel. I've been told that the group's will shrink more with a couple of turns or so. I haven't been back to the range to give it try. The rifle already shot well enough for my needs group wise, I'm just tickeled that all those 1" groups now land in the same place! Good product, but on my next No.1, I'd like to do it at home with a simple screw through the hanger.
