I think Jack is winning but I do not think that means he was correct and Elmer incorrect.

Market trends reflect the short case-high velocity cartridge that can easily be represented in the common rags and glorified by the "expert" writers. This makes it much easier to shove these 'been done already' cartridges upon the average hunter who really has no in depth knowledge of ballistics and terminal performance of projectiles.

I'll be stayin' in Elmer's camp....
