While developing a spreadsheet of energy and trajectories of the most common calibers to facilitate a rifle purchase, I marveled at the energy listed for big bore calibers like the 45-70 vs. the 30-06, 270, etc. and I remembered the debates about velocity vs. "knockdown" back in the 80s and 90s. So I started wondering if there was another way to quantify the true 'killing power' of the choices when comparing cartridges. Unfortunately, mass x acceleration just doesn't rell the while story. For example, I know a 150gr 7mm mag soft point running around 2800 fps will spin a good sized hog around and take him right down. But I've also heard stories from my brother's inlaws and guide friends about 45-70 or 444 rounds running far slower and listing far less energy figures literally knocking a mule deer off its' feet.
I realize dead is dead. But is there a way to quantify the kind of 'knockdown power' I would gain if I bought a Marlin 45-70XLR or 444XLR over my 7600 in 270?
