Rock Creek are nothing special. have had 2 of them and will not be getting anymore. Not worth waiting to get a average barrel. Lots of better options out there.
average 100 yard 3" group on a paper plate hunters certainly won't notice the difference between Rock Creek and Douglas barrels
I haven't been able to tell much difference with any "name" brand barrel...some may clean a little easier but that's about it.
The "best" I've seen so far was a Proof Steel barrel in 6.5x284...it legit went 1/4moa straight off the lathe with the very first 3 shots out of it (after 1 test fire)...a Nosler Partition too...on a Rem 700.
I definitely can't tell the difference between Cut and Button...I most certainly wouldn't let one sway my decision.
