Now, how do you put the projectile on target at 100 to 200 miles? Is your target moving or stationary?

Fire several. A guided missile costs hundreds of thousands or millions of dollars each. A block of iron is a bit cheaper. You could probably throw iron blocks for a year for the cost of a cruise missile.

In order to hit its target at 100 to 300 miles, the EMRG projectile has to have a guidance system that is active in real time and can take the g-forces associated with its launch to Mach 7 velocity.

Targeting will have to be done by a drone or satellite. Both methods have their strengths and weaknesses. Guided projectiles, whether fired from conventional guns or the EMRG are expensive -- and the cost goes up because of the long range guidance (drone or satellite) involved. Individual projectiles -- round for round -- aren't as expensive as a single guided missle, but they're miniaturized cousins.

The guided 5-inch (127mm), 6.1-inch (155mm) or EMRG projectiles are precision guided rounds that are smaller and lighter than missiles — but this does NOT translate into cheaper target killers — unless you compare one missile to one projectile. This comparison is an apple vs. orange duplicitous argument.
