Well today I mounted my NIB. 336XLR-35R & NIB 2x7x33 Redfield. I boresighted it in with a Bushnell boresighter. The scope was 11" low and to the left 1" at 1/4 MOA this meant 44 clicks to bring it up to zero. This wasn't a problem the scope zero perfectly. But I thought why not use the shims Marlin furnished with the rifle and save the adjustments. There were three shims in the envelope and I installed all three. I put a mirror against the objective lens looked through the scope and put it back to factory zero. Okay now lets see where I am. I was now only 2" low and 1" left, 8 clicks up and 4 clicks to the right. I saved 9" of elevation.
Now before anyone start to wonder about the dreaded barrel droop this 336XLR-35R is a 9321XXX serial No. which means it a 2007 vintage. I have read many years ago that shims should be used to compensate for variation in machined surface if needed to save scope adjustments. there is four contact machined surfaces [1] receiver to [2] base to [3] rings to [4] scope.
At the range I'll see if it needs to come up more or take a shim or two off.
