Sorry but IMO thats stupid.
Look at all the small bore's that have killed deer, elk, bear and moose.
.22 Hornet
.223 Rem
.22-250 Rem
.220 Swift
.243 Winchester and so on...
Heck, look at the .30-30 and .250 Savage, those 2 calibers have killed more big animals such as bear and elk than you could ever imagine.
God Bless ya, Jeepy, opinions are like rectums, everybody's got one and everyone is entitled to one. Thank god you are arguing for the "other side" it would be way too much damage control to have you arguing on mine!
Regarding Mr. Walter Dalrymple Maitland Bell you've already got part of the story wrong; SpyroAndes has one of the key pieces --- solids that are ILLEGAL here in the USA and Canada, but there is more. How about you do a book report and get back to us with the REAL story about this extraordinary individual (He blows Jack O'Connor into the weeds)! For those that know the full set of details on Mr. W.D.M. Bell it does make for the classic Paul Harvey line, ...."and now you know the rest of the story!"
