Is the lowest impact velocity for expansion yet known/claimed for the new "404"gr/.458 ?
It appears from multiple examples cited by individuals (including myself) that the "book" claimed impact velocity for expansion doesn't always "fit" personal experience, both ways (above or below). Of course, the medium used (water, ballistic gel, animal flesh and bone, etc) is the greatest influence on real results.
Perhaps Sir Ron could chime in here for his view/experience, and/or any others.
