Good points made here. I must add one more point. Useing the biggest caliber out there in no way qauretees a quick clean kill on any animal big or small. Shot placement and adequate penetration is what it takes. Many guns are capable of doing just that if the shooter does his part. I have no problem with people who want to use a 340 Weatherby for whitetails. AS long as they are not doing it thinking that a cannon will make up for lack of skill. Believe me there are many out there who think just that. I quided quite a few of these mental midgets for deer hunting trips. I have yet to see one take their deer with a stick but many of them could have done just as well to use them. There were idiots useing small calibers as well.
