Just a heads up, LE and Mil adopting a new cartridge is not as easy as liking a forum posting. There are so many miles of bureaucracy to deal with its tiring. The creedmoor is revered by many shooters in LE as well as group. Unfortunately, millions of cartridges as well as weapons stand in the way of a single cartridges adoption.I thought the popcorn idea might take off.
The point of my devils advocate question is that if the creeds are so good seems like LE and the military would be all over them. As far as I know they don't use them, so the 308, and 223/556 must still be pretty good!
I get wanting to play with different stuff like the creeds and wildcats,been there done that, but in my older age, I am coming back to the simple. proven stuff and enjoying it.
As a creedmoor shooter, I have a love for what works. With that, my latest rifle is chambered in 308. Why? Because it still works. Being a supporter for a cartridge is fine. Pooping on someone else's opinion regarding something that doesn't effect you is just silly.
I have killed many animals with both carts. One doesn't stop killing because the marketing of something newer.
just my .02
ps, the 300WM is heavily used by SOF shooters.
