my first 742 case rebuild, need alittle advice please

Sorry to hear about Your dog dude, that sucks, that's doin' the right thing. I agree, set the best coast pattern & try 'em. The reality is that, like everything else in production,
these cases are not T-totally perfect. It doesn't take much variation in the accuracy & squareness to skew the nose of the pinion in both windage & elevation. I asked about
the case because there is a tiny chance it has been troublesome to set up before, thus sitting around empty & unused, not likely but still possible. Kudos for Your perseverance.
