I've had one since last fall.
How did you get the 223 bullets to register?
No trouble with 243/105's and up.
The BC can be calculated as the unit gives velocities at several points along its path, then can be back-engineered to get a BC, easy with the aid of a ballistic program.
Concur with everything the OP stated.
