My scout rifle is a Rem 700 ADL 3006 with a factory polymer stock and with what appears to be a very early lyman 48 with the flip up reticle, 125 slide and a Thompkins globe front sight. Barrel cut to 19" with fresh muzzle crown. I have set it up with a Bushnell Banner 1.75-4x32 scope #611436 and QD rings. Boolet is a Lee for 303 Brit sized to 311. At 50 yds 3 shots will be 3/8" to 1/2". 21 gr 2400 load in FC brass.
Eyes are still good enough to use the irons as primary.
The sight is tight and holds zero but I suspect it is not a correct matchup. Does not matter if not correct as I am happy.
Question is how do I figure out what approximate MOA each mark on the slide is? Am interested in 300 yd shots. According to JBM Ballistics, with a 1850 fps velocity, and 100 yd zero, 25 yds is -0.2 MOA, 150 is -2.7 MOA, 200 is -5.9MOA and 300 is 14 MOA. plan to round up to next even # for the elevation clicks.
Pls accept apologies for long winded question. )
