The eye box tends to get smaller on higher magnifications.

It sounds to me like your scope is set to far forward or back.
And or your stock needs adjusting.

Find your natural position on the stock and move the scope back and forward until you have it in the middle of the two positions where you start to loose a full picture. Do this on high power. You should now naturally be in the middle of the eyebox when you look threw the scope.

VC, i don't know whether Parallax is the right terminology for what was occurring but there was increasing blackness and tunnelling effect. Are you suggesting to loosen the scope rings and move the scope back and forward until this problem goes away and then tighten it back down?
