This may be an interesting thread...........

I read Dave Estergaard's report on various penetration tests with great interest.

It seems the conventional solids OUT-PENETRATED the monolithics by a goodly amount..... HUMM??

Granted plywood isn't a Buff! But then friction is friction however in a common substance.

I have often thought that only sectional density was lacking something when comparing less DENSE and LONGER monolithic and more dense heavy core bullets of the same weight and sectional density. If Estergaard's report is somehow comparable to "feet" penetrated into an elephant with the different bullet types; then Speer may have the very best idea by using the densest material.
This hinges on the solid not deforming however. Any thoughts?
