I hope never. Otherwise things will get pretty stale. Look forward to new stuff arriving on the shooting scene.
Guns yes, cartridges... ok, sure i can agree... but like I said these new rounds aren't really doing anything different than whats been available for years isn't that exciting to me. The window for newness is really small when it comes to cartridges. My opinion is biased though because I fell for it many years ago with my 2506... learned the hard way that flatness doesnt make you a better shooter. The rifle I spent years making memories with I wish was better suited to the elk I hunt with it. My guess is years from now the new CM will fall into the same category as other wildcats turned production, the old timers will swear by it though.
