thanks for the input guys. Allow me to attempt to be more informative. Firstly, this is my first rifle without open sights and was taught the artillery hold at age 11 or 12. I was trying to do some final zeroing in of the scope as I figured it was pointless untill it was broke in. For this I was using a couple 50# bags of chicken feed as a bench rest in a kneeling/squatting position but I 'normally' shoot standing. Yes, the rifle has a picatinney rail. All scope mounting hardware was present and cranked down. I did check my stock screws when the issue first happened one was marginally loose so I cranked that down. The first indicator that I had a problem was a very very loud report on a shot after that the muzzel took up quite a bit of the sight picture when I couldn't see it at all before so I figured it was some last bit of dieseling and maybe I bumped the scope or something so I unmounted the scope and the rings, remounted them and tried to re zero at 20 and 50 yards with crossman .22 14.3g hollowpoints and had no luck. Even when I ended up with the elevation knob all the way down and windage all the way out, she was still shooting about 3 feet high and 9 inches left. SO I went and got a different scope I dont use from my other springer and tried that one. Similar issues but there was some improvement.
