Bigrx and Nframe,
The FMJ with taper will possibly perform better on wood tests than the monos, since they are pointier.

This advantage may not be apparent in fluid where flatpoints and blunter noses(theoretically) maintain better course.

Saeed had pictures on AR of Barnes solids or a-square monos with bulging noses and slightly bent I believe.

As to the african grad slam it obviously works but is a bit of an over engineered gimmick. Or rather a good excuse to bump of the price for a 'short bullet'.
The original purpose of expensive tunsgten carbide cores is to penetrate armour in military calibres.
