I have cleaned the barrel three times. I have tried three different brand 10.3gr pellets and three moderators. Tuned 2nd reg from 85 to 120. Adjusted mirco and macro. I have moved slow, been patient. Adjusted VA from 4 down to 1 Watched numerous tuning videos. Factory setting : 150, 120, 16, 2.5, line 4. tried speeds from 840 to 940 aimed for 875. Unable to get tight ES, most often a 30 +spread . When I shoot 25-35 yds, , get a couple fair shots and intermittently flyers, sometimes 10 inches off. Checked the probe and mag. Had the rifle one year, passed thru 12,000 pellets. Maybe wore it out ? Great performance and accuracy up until 2 months ago. I like to tinker but enough. I am at wits end, ready to send to FX for repair and pro tune. BUT, wanted to check here first for any suggestions ? Thanks.
