I would really like to know what bullet, 215 Berger or otherwise in .30 cal that is not affected entering the transonic zone. I'm building a 300 PRC for 2100 yards and the more research I do the more I seem to find out that VLD bullets do not transition well at all. So anything with a more secant ogive is more prone to disruption in flight. Does that include hybrid designs as well? Where do you draw the line between tangent and secant ogives before the transonic performance is compromised?
