I read the match bullets for hunting and 223 TMK threads. They were brilliant, and changed the way I think about terminal performance. Unfortunately, I am restricted to non-lead bullets. Some follow-up questions and threads have come up on this topic, but as far as I can tell my specific question has not been addressed:
Is wound channel size for a copper mono purely a function of bullet caliber (edit: at fixed impact velocity)?
Example 1: Take a 150 gr bullet in both .308 and .284 cal (e.g. barnes TTSX). The .308 is wider, but the .284 is longer, so perhaps it could have similar frontal area upon opening (longer "petals")? Hold impact velocity constant.
Example 2: Sticking with TTSX, setting bc and velocity considerations aside to focus only on terminal performance, is there any difference in frontal area (expanded bullet) between say 120 gr and 150 gr .284 cal bullets? Hold impact velocity constant. Again here I am wondering if length/mass factors in to the expanded surface area and wounding potential of the bullet.
I ask this question because I think that it would be reasonably easy to test empirically, but I do not have the resources. I am aware that this could differ by manufacturer, and perhaps even within a line of bullets depending on design. Appreciate any insight.
