The only thing I don't like about calibers like this is the fact that someone is always stealing other people's ideas, renaming it, and taking credit for them. I am not sure which came first the Yeti or the Reapers. The Reapers have been around for a while so I kind of lean towards the Yeti being a copycat. The Reaper lines make several calibers off .308 brass. Think the .375 Reaper may be their biggest draw. But, I haven't checked out their site for a LONG time.
