Whats worse I am now using a quality scope, instead of my old Deben Target 10-40×50, so everything is in sharp focus and crystal clear. Maybe I should try using my shooting glasses with the scope to correct the little bit of astigmatisim I have. I suppose that I would also have to reset the eyepice focus as well though.

Alan, were you shooting air or cartridge? irrespective, this may well be mirage!

I would not use your shooting glasses with a scope. Astigmatism will only be noticeable when trying to align circles in shooting, so will make them look oval or elliptical.
