Erik,



I am glad you asked!



The esteemed Norbert Hansen has performed research on which type of solid penetrates best in animal tissue (aqueous media). Note that the penetration through soft tissue operates by different mechanical principles than penetration through bone. A bullet penetrates through soft animal tissue by forming a vapor bubble in which the bullet travels. The bigger the vapor bubble, the deeper the penetration. Likewise and generally speaking, the larger the flat meplat on the bullet, the larger the vapor bubble and the deeper the penetration (assuming no bones are hit).



This research is written up here: http://www.grosswildjagd.de/penetrat.htm



In Mr. Hansen's research he noted that a solid that is generally a round nose but which has a flat meplat at its end did not penetrate any better than a round nose. He said, "[A] meplat formed only by cutting a hemispherical RN shows no effect."



A frusto-conical solid penetrated deeper, and a solid with a superpenetrator disc (see link above) penetrated deepest of all.



Based on this research, I would expect the GS solids to penetrate deeper than the Rhino solids.

Thanks for the info Dan! One thing I was wondering about though is that Norbert Hansens research shows how a solid acts through soft tissue as you wrote, and showed that the frusto-conical solid penetrates best (learned a new word today... ). But you mentioned that bone was another matter. So would that mean that shooting an elephant in the head would be best with a non frusto-conical solid? Or does it also work the best for this too? Or is the honeycombed skull of an elephant a bit of both principles since I presume that the open areas in the "honeycombed" bone are liquid filled?



EDIT: another thing that just crossed my mind is what about the chain of thought that firing moly-coated bullets together with non coated bullets (such as a soft first, followed by 2 solids) isn't a good idea? It appears to me that most people feel that the moly should be cleaned before firing regular bullets and vice versa? Or wouldn't that mean much in a hunting trip situation?



Here are some pictures of the Rhino monolithic solids (two is next to a molycoated Rhino 380 grain .375 bullet)

According to the info I have from Rhino, their solid brass bullet has 5% lead in the brass to "smoothen"/lubricate the bullet. Nonsence? A valid idea? Or something that all monomental brass solids have?
