In reading your initial post about the lighter weight bullets and kind of reading between the lines about your comments on the 200 grain bullets let me say this.
If you’re new to the long range hunting scene and have always shot 150 grain bullets as maximum weights in a 7mm you need to understand the design and concept of the heavy for caliber bullets.
The Wildcats, or any other brand, that are designed for very long range are long, sleek, wind bucking, velocity retaining missles with before unheard of BC's. Old time 200 grain bullets, which were never available in 7mm, were round nosed, blunt, clumsy and shot like a rock. The new ULD RBBT’s or other dedicated long range bullets not only perform at very long range but also at reduced ranges under most conditions. You just need the horsepower to get the upper velocity levels from the heavy for caliber bullets. That's where the 7mm AM case comes into play.
Here is a picture of a 200 grain Wildcat ULD RBBT beside a Nosler 160 grain Accubond, both in 7mm.
Here is the 169.5 Wildcat 7mm and Nosler 160 Accubond flanked by the Wildcat 200 grain ULD RBBT’s for some more comparison.
Good luck in your quest for the new long range rifle. The design and planning stages will keep you busy for quite a while.
