With the advent of the super premium bullets - for example, North Fork, GMX, TTSX, etc, any good hunter/shot could reliably take ANY game in North America, and quite easily too. One shot would be all that is needed - using a .243 or 6mm Rem. Of course, these 'super' bullets would only be necessary for the big bears - all else being handled with 'lesser' bullets.

What makes life more interesting, is using a variety of rifles and ctgs. - or having specific rifles for each animal we hunt, even though a variety of different cartridges aren't required.

Thus, if many 'of us' could make due with a lowly 'varmint/deer' ctg. for all NA game, most would also make due with a .308, '06 or in the Euro rounds, a 7mm or 8mm Mauser. Anything bigger is simply not needed - but - is fun. That is the reason for the plethora of rifle ctgs. today - something for everyone.

They will work perfectly, if applied appropriately.
