[QUOTE="fmajor, post: 1107610, member: 20646"] 'Morning Muddy - I didn't say the 300 Winny is [U]vastly[/U] superior to the 7mmRem, just superior. I guess I should have been more specific in what I was thinking than merely stating one is superior to the other.... I was thinking the 300 Win is generally a more lethal chambering than the 7mm Rem. Nah - there's much more to calculating/estimating lethality in a projectile than simple BC (which is simply a derivative of drag coefficient, velocity, etc.) and equal for weight velocities (size and weight do matter as does sectional density of the projectile). I suppose by "equal weight-for-caliber" you're meaning the ratio derived from a projectile's weight to it's diameter. This then is used to compare with another projectile with an "equal weight-for-caliber" ratio (the 300 Win and the 7mm Rem in this instance). Further, I'm guessing you are saying "equal" in terms lethality (between the 300 Win and 7mm Rem). In this instance, these two "equal weight-for-caliber" projectiles are moving at the same velocity and therefore must be equally lethal. Unfortunately, that's a value that isn't truly linear in effect despite the simplistic mathematical modeling theories. Heck, that's a subject that's been hotly debated since, well, since folks started slinging stuff at animals to kill 'em! What we actually want to know is how effectively a projectile will kill. This is very challenging (impossible?) to calculate because it relies on many variables - not the least is determining a projectiles ability to retain momentum as it travels [U]through[/U] a given medium (hint: current retained energy mathematical modeling is insufficient for this due to differences in media as relating to the medium's density, material elasticity, etc). Retained energy itself is reasonably straight-forward to calculate. However, no one has yet come up with/published a mathematical model which accurately calculates retained energy as a projectile travels *through* a medium after it's initial impact. This is aside from whether or not that projectile can/will induce lethality. Taylor, Fackler, et al have done extensive research on this topic, but fail to come to consensus (or even have their research pass peer-level review) on the characteristics of a projectile which consistently induces lethality - only what a projectile needs to do. Yep - I agree!!! It sure has helped me with shot placement - especially when I was in uniform and had to take an "off-the-rack" rifle that never came home with me (I like to snuggle on the couch with 'em :D!!!) ... Confidence with and knowing my gear was about all I had (well, a fair bit of practice as well). [/QUOTE]
