OK, my 2 cents.. I generally agree with everything stated: a couple issues though –
I have suspect the windage is off due to the rifle’s scope mounting holes are out of alignment with the bore centerline, I’d believe this normally would not be a problem with a 5R, however, it’s a thought.
If the screw hole taps are out of alignment you may not want to loctite the base down at this point now that you know yo have a problem.. Try drymounting everything to about 90% AFTER EVERYTHING ELSE IS METICULOUSLY CHECKED..then, boresight at 50 yds and check scope’s line of sight, if its off paper (you see paper through bore, but crosshairs not on paper), you may indeed have the mounting screw holes out of alignment, fire a few shots first to dbl check.. there is no ‘quick fix’ for this..
Nobody mentioned (I don’t think) about mechanically centering your scope . Do it first before anything
. (check out swfa’s site & forum for good info). If the erector is messed up you may need sending it back or if it was damaged by ‘pizza boy’ then you may have a very expensive useless optical ornament on your hands.. (during boresighting and scope line of sighting, and during your first few shots at 50 yds you aren’t seeing it track at all, you have a messed up tube – assuming you’re on paper).. there are plenty of videos on zeroing properly, see swfa, Midway USA and also u-toob websites..
Also, check you mounted the base correctly, (not backwards).
Ps. here’s a link , its well worth reading through carefully as well as other areas on the site..
