Drilling Man:
Enjoyed your post about the penetrating qualities of the 30-06 200NP's and how it out penetrated the 8x57 and other larger rounds as well.
Finn Agaard, a former professional hunter from Kenya who migrated to the US when hunting was outlawed in Kenya, did a lot of testing and his findings about the 30-06 200 gr. NP was the same as yours. His published results shows that it was as good a penetrator as the .375, 458, etc. He never wrote about the 8x57 , but your experience would seem to settle that issue. Agaard commented several times on what a really great load the 30-06 /200NP was.
