Jorge 'ol buddy I got your slack. You just need to get back to the basics and bunt for the next few at bats until you get your mojo back. If you've been doing most of your shooting off hand and getting frustrating results then it's time to get yourself to the bench where you can determine if the rifle or the scope really has a problem--or not. Take one rifle and (don't even look at any others) get yourself comfortable with a proper rest that won't skew your results, and start shooting at those 10 yd targets. If you can't easily keep a group waay under 1/2 inch at that distance, then start looking for loose screws,dirty barrel,proper posture,eye relief, etc as a possible cause. If the gun and sights check out OK but you still can't shoot a tight ten yard group, then take a good look at the guy behind the trigger. Even bad pellets should shoot pretty tight at 10 yds so get your zen face on, be properly fed, well rested, well hydrated and calm. Clear the distractions from your mind and start shooting. Take your time. When you master good groups from the comfortable rest then you KNOW there's no problem with the rifle, then you can go back to the more difficult offhand shooting. We all have days when our heart rate just doesn't want to settle down and we bounce around on that target. Don't sweat it. Tomorrow is another day.
