Scope dope is what he's talking about. In a nutshell, it's a preset card with different ballistics of different rounds. Making a long story short, one might have a "primary load" that hits the center each and every time. Basically, your zero load. A dope card can (or will) give you ballistic data on a different load and what adjustments are needed to hit where you're aiming.
I.E. your "go to zero load" is your 62 grain stuff. You'd have a dope card that gives data for longer range shooting (holdovers, drop, drift, etc) with that load and also can give data (five clicks up, two right type of thing) for different loads like your M193 spec stuff. It allows you to "reset" your zero to a different type and weight of round without having to fire a round to confirm it since you already did it in advance.
You can have dope cards for a single load (windage and other environmental factors) or multiple dope cards for different rounds you might fire. It's not bad to keep track of such things if you routinely engage long range targets. Long range is obviously dependent on the rifle and caliber you are using.
A tall target test is a test to determine if your scope clicks are what the manufacturer says it is (1/4 MOA, 1/2 MOA, 1 mil, etc).

It's nice to know exactly how your scope dials in, but...we're talking dedicated long range shooting stuff here. Like normally further than you'll be expected to engage. My opinion of course.
