hawke SW

I"m having trouble with getting a clear picture on my Wildcat, FX limited rings, and Hawke SW scope. We can not find the cross hires on low power on the SW 6 to 20 mil dot. Been using scopes for over 50 years but have not found the sweet spot for the eye release on this scope??? It should be easy to find on low power but not??? Does it have something to age over 66, eye are great 10/20 but need glasses to read but not that bad or I'm I just too big for the Wildcat, 6'5" over 300 in great shape for someone over 66, still working just because we enjoy what we are doing.

We are use to having raise the rifle and scope is ready, but not.That on all brand of high end scopes we own and that on all our powder burner,rifle and long range pistols and other air rifles. We know how to use a scope but this one is getting the best of me. We have set up pistol for 500M matches and rifle for long range hunting. 

So the old man needs a little help on this one!!!!
