So I loaded 16 of the SST 125gr (thats all I had on hand) and shot today. I shot the SSTs listed above, 168gr FGMM, 175gr FGMM, and 178gr Horn Precision Hunter. The day started like garbage. Had the exact same groups as before which was anywhere between 1.5-2”. I knew the rifle shot better because of the proof targets sent to me by Q but had no idea what I was doing wrong. I decided to completely change the way I shot the rifle because at this point what do I have to lose? I loosely put the stock in my shoulder, lightly placed my cheek on the riser, and lightly placed my non-shooting hand on top of the optic. Instantly groups tightened up. I really think thats the key with this rifle. Let it beat you up when you shoot and hold it loosely. I’m headed back out next weekend to make sure things are consistent but here was the last 5 round group of the day I shot with the 168gr FGMM. I can work with that. The 125gr was by far the most accurate when I was doing everything wrong and I look forward to seeing what groups I get now that I somewhat have it figured out. Thanks @66427vette for the data.
