Just read this article yesterday. It may give you ideas. https://www.fieldandstream.com/10-most-accurate-factory-hunting-rifles-weve-ever-tested/
What will be this rifles job?
You didn’t say how much your budget is but I’m guessing by the interest in the Browning-Mcmillan that you don’t have a problem dropping $2500 on a rifle? If going to that extent I think I would find a Remington action & have a 300 Rum built for not much more money. If your wanting the rifle ASAP then I’d look at a Christianson arms or the Browning with some trigger work done.
