yeah redhawk it certainly wont' be a debate ending anytime soon, and i guess it's how one frames their experiences and comes out of learning experiences. one side thinks that bigger would've worked better the other sees all big bore pistols working well and not much difference b/w them.
i'm a big believer in a tight spot when something needs to be stopped it needs a CNS hit, not a bigger bullet. i think we all agree that big bore pistols kill really really well and waaaaay out of proportion to their ft/lbs numbers would imply. that said, i think we'd all agree a .416 rigby hits with a mighty wallup that no pistol will match. that said, a .416 in the chest won't stop a bear and neither will a .500 smith. however, a .44 mag to the cns will stop anything that walks. 240 grains at about 1250 fps has stopped just about anything that walks.
so let's sum up this little scenario. you're fishing in alaska and you've got two young sons and a little daughter with you. a big brownie charges across the stream at you. this same size bear has not been stopped immediately in the past with several .375's and 416's to the chest. what do you do, well i'm putting a .44 or .45 caliber hole dead on in the head and seeing as they're medium recoiling hardcasts i'm putting 2 or 3 in the head trying for b/w the eyes. scenario #2 is at this time that you realize noooooooo handgun or rifle is gonna stop him unless you put the bullet in the brain. you realize that you could not stop him with any firearm in the chest and you left your big 500 smith at camp cuz it's just toooo big to carry along with all the gear you gotta carry for your youngest daughter. the third worse scenario is that you've bought into the bigbore mania hook line and sinker and get your one or two max shots off with the big 500 linebaugh and you put them into the chest expecting the best b/c after all it's a .500 isn't it!!!!! it's then you realize you had to hit the CNS or there's no guarantee of any stoppage and you should've paid more attention to the mark sullivan dvd's out despite the bravado present on them..........about that time the bear hit's you and starts munching and you die wondering what will become of your screaming kiddos after you're gone.
i've not shot cape buff yet, but i have shot american bison, a couple problem bulls for relatives that ranch over the years and hogs that went upwards of 500 lbs and to be honest, i've truly not seen a huge difference b/w any of the big pistol rounds when loaded appropriately. that is to say, i think everyone is kidding themselves if they think there's any perceptible difference on game b/w a 420 gr 475 round at 1350fps and a 335 grain 45 caliber round at 1600fps. i've not seen it yet. the bison my friends have shot with rifles ran off and died the same as mine shot with pistol hardcasts whether it was my 454 or 475 or my bud's 500 smith. now, being in west texas there sure is a trajectory difference and that's why i feel the king's out here are the 454 in a normal size packing pistol and the 460 for a larger gun size. i've heard alot about how the 460 is a worthless round and to buy the 500 but anyone shooting out in west or south texas from a blind will tell you the 460 is vastly superior to the 500.
