I have 2 rifles in 6 dasher, in case that matters... Both have stocks that measure .625 +/- on the flat bottom . Being new to bench shoot shooting, I am confused to what ear spacing I should get on the rear bag....my thinking is .625, but I've seen conflicting advice on "running on the stitching". This is an Edgewood bag with the slick ear material ....please give any advice or criticism that is justified... Thanks for any help...rsbhunter
