Hi all,
I was guilty the other day of "scope shadowing." To those uninformed, which included me and I've been shooting for over 50 years, this is when you don't have your eye close enough to the scope and therefore don't get a full field of view. I've read that it effects accuracy. I was shooting my 7mm WSM and with some loads I got wacked on my glasses. My scope is a 3x9 Bushnell Elite 4200 and at 9x doesn't afford enough eye relief to some of my 7mm WSM loads so I resorted to backing my head back a bit to give me more eye relief. I should have backed off from 9x to 7x but didn't. A month ago, starting with N204 and 154 grain slugs, my starting load of 58.0 grains gave me a 1.0" group which was better than I was getting with a couple of other powders so I thought I was on the start of a good combo. For my next session, I loaded 58.5 to 60 grains in 1/2 grain increments. 58.5 gave me a 2.6" group, 59 grains gave me a .369" group (all touching), 59.5 gave me 1.95" and 60.0 was 1.5" I was dumbfounded at the group variation. Could the "Scope Shadowing" t be the reason I couldn't duplicate the .369" group or even the 1" group? Thanks.
