This is a new gun with 20 rnds. of Winchester 150 grn. Power Points, and 18 rnds. of Hornady 168gn. A-Max over 42 grns.of Varget so 38 rounds total. I'm using a Nikon Monarch 4x16x40 with a set of DNZ Game Reaper ring/base combo. I fired the 18 reloads the next day after another good bore scrubbing. At 50yds. the first 3 round group was one ragged hole less than .5" so, I thought everything was fine and it was going to start grouping. When I moved out to 100yds. using same load, I readjusted my side focus/parallax I checked real close by moving my head and watching for movement in crosshairs till there was none. I then looked at the adjustment knob and it was right on 100yds. The problem was I was hitting all over the target with nothing resembling a group. I did have a couple go close together maybe far left then maybe a couple more far low or high or right? When I was maybe an inch to the left of POA I turned the windage 4 clicks to the right and wound up 2" or more to the right? I've checked all base and ring screws for tightness and no slipping by marking with pencil. Also, I relieved a little material at the tip of the forearm so the stock would no longer make contact with the barrel while on bipod or rest as mentioned by others on another forum. They also, said get rid of the junk stock but, I'm on a fixed budget and would sure hate to waste another $200.00 or so for a Bell & Carlson stock and still have save problems or even worse. I thought about taking my Weaver t36 off of my CZ 527 in .204 and trying it. But, adjusting parallax by eye and it was right on the 100yd. mark on the adjustment knob makes me wonder if it's worth the trouble of trying the Weaver or not? I sure would appreciate any suggestions as I just don't know what to do. Thank You!
