I moved a few months ago into a house that has an odd basement. I can't get a 10m distance set up without peturbing the wife. I was able to set it up at 7 yards. I did the math and the target should be reduced down to 64% to give the corrected sight picture. My question is: "Is there anything detrimental in doing this other than having to make my own targets?". This is a theoretical exercise only because I don't have another option, other than divorce.
