Just went through the whole 'shimming' experience.
To 'lower' your POI, shim UNDER the scope on the front ring.
A soda bottle or other adult beverage aluminum can will give you a shim that will change POI about 4". Cut about 1/2-1" long strip, narrow enough to 'hide' under your scope. I'd think 2 shims, maybe 3 will get you where you need to be. Probably just 2.
