Lead sleds rattle scopes to #### esp if your using a 7mm rem mag. Get your shelf a front and rear bag rest and a good shoulder pad.
A zeiss scope with that much inconsistency leads me to believe that it isnt the rig, its you. Unless of course you have cheap mounts and rings that are improperly mounted.
I have a hard time believing an 8 moa group at 100 yards or larger is 100% shooter related.... I'm concerned something is loose or broken on the rifle and or scope.
Seeing how the rifle is previously loved, and you are not at the range, I'd disassemble the rifle, re-torque all of the screws (rails screws, action screws, scope rings, absolutely everything) and do as complete a cleaning as I was capable of doing. then I'd go to the range with a buddy and have us both fire off some groups and see what, if anything changed between him and I.
What's the deal with the scope? is it known good? can it be mounted to another rifle for testing purposes?
Did the previous owner supply the rifle and scope? or just the rifle? Maybe I missed it, what is the scope?
Just let someone else try it... JP.
Used rifle, with supposed low shot count. And a new scope that did not come in a box, nor with manuals. It was supposed to be a display model. It is a 6.5-20x 50mm conquest MC, with a Rapid Z reticle.
I will pull the stock off of it this weekend and have a look inside. Not sure what a crown is, I will have to Google that.
I have a hard time believing that a 7mmRM recoil is too heavy for a conquest scope, but il keep it out of the lead sled anyway. So far I've only put 60 shots downrange, box and a half, cleaned it, and then another box and a half.
