This is not a "vs" thread. I have read Rathcombe, I have read Chuck Hawks and I have read Ballistics Studies (the latter being my favourite), I have a reasonable handle on the theories relating to wounding and why velocity may be important.
My question is what are the competing theories indicating "heavy and slow" cartridge/bullet selection? Is it simply increased penetration and potentially greater (if less rapid) overall expansion resulting resulting in greater wound surface area and more rapid bleed out? Or is there more to it? If that is the case then would this not be contra-indicated by the potential for over-penetration on light bodied game?
