Thats my take on it personally. Thats exactly why I"m putting one together.
some rounds are quieter than others and bore diameter vs pressure is an issue to my ears. But supersonic is just loud to me regardless mostly.
I'd go for what you need to use it for personally. I have a 50 beowulf upper that I use mostly in swamps as I want a big hole to start with and then expansion.... trailing blood in water sometimes kinda sucks...
If I wanted longer range, I've shot the Grendel type rounds out to 600 yards very easily before. Did some of the test firing for the Grendel when it was still 6.5 ppc.... I don't have one, but will at some point.
