I think they are here to stay..I here and read lots of interesting stories about wildcatting and using long barrels to eek out those last few FPS. As far as I know they are the fastest Short action rounds available so that makes them king of the hill..
My real interest is in the .270 variety..so far I haven't been disappointed in its performance and ease of finding a good shooting load.
I'll be testing some 150's tomorrow I hope..
