I've had one for a decade. You need to reload in my opinion. I was switching to 28 Nosler and had all the components but decided to use the same reload strategy for the stw and it worked out; 195 Bergers and N570. It's a barrel burner though. I buy nosler blem brass once/year when it comes out, bullets, powder, and primers have been pretty easy to get.
The 7PRC is the easy button, decent speed with semi heavies and way less powder than the stw.
