There have been a few new wildcat cartridges of late:
22 Creedmoor
22 Nosler
6.8 Western
6.5 PRC
6.5 Bitch Cat
Just to name a very few. I get that if we're not trying who knows what kind of break through we might miss out on.
But for many of these cartridges, on post-development and research but pre-production of dies, barrels, and brass for the masses do they ask the question, "does this cartridge offer something no other cartridge offers?". Or is it the cool factor?
