Well it wont bud,the lazer is just like a boresighter,just to get you roughly on target,it sounds like a scope/mounts issue,if you want to test the rifle,clamp it down,securely without the scope on,look down the bore and line that up with your target/backstop,then fire 5 rounds and see how she groups,if that is not possible,swap the scope and mounts,and try zeroing conventionaly,ie boresight/lazer alighn,then tweak it from there,obviously difficult to tell,without being there, but it is sounding like the scope or mounts mate,even more so as you say it was fine before,good luck let us know how
