I know the difference between FFP & SFP and should've mentioned that this will be a fixed power scope (Leupold, Sightron, Weaver, or SWFA SS).
Instead of saying "Learn", I should have said get use to the clicks being .10 and a full Mil being 3.6" at 100 yds (36" @1000) over the Minute of Angle that I've used all my life.
I never cared much for using hash, mil dots, etc for holdovers as I perfer to dial at the range.
However, I can see their advantage in the field (hunting) or for measuring, but to be honest, most of my shots are under 200 yds (that's a different subject too) in the field.
Thanks for the replies thus far.
