I’m at a loss so hopefully someone here has the answer. I was shooting my Ultralite in 28 Nosler today attempting to zero in at 200yds. I was on paper and finally had a group starting where I wanted it when I threw a flyer about 7 in low. I figured it was me so I shot again and didn’t even hit paper. Same with my next two shots. I then had my friend shoot and he couldn’t hit paper either. We went from a 3 shot 1in group to not being on paper in 3 shots and 4 min. We had let the barrel cool off but it was hot. I was running the Omega can from SilencerCo. All screws and bolts were tight on gun and scope. I did notice the bolt was hard to bring back but that was happening all day. I don’t even know where to start. TIA
