The second edition of Litz' book is very good and fairly easy to understand. There are a few errors but he gives a good explanation of the difference between secant and tangent ogive bullets and the ballistic differences between shorter and longer boat-tailed projos.

I am guessing but Litz and Berger have done extensive recent original art designing "Hybrid" bullet profiles, melding what they consider the best of both tangent and secant ogives. I assume that's what they've done with the 175.

My experience with 300-grain .338 Lapua Magnum projos has Sierra Match Kings running out of steam around 1600 Meters (they definitely do NOT fly true transitioning thru trans-sonic); Bergers around 1800; and Lapua Scenars right about 2 klicks (all using the same primer, brass, and powder charges).

RUAG (Switzerland) has a new proprietary 300-grainer they are adding to their Swiss-P line that is aimed at meeting USSOCOM's 1500-meter PSR spec as well.
