I'll vote .300 WSM stainless synthetic in anything other than Remington 700.
I have a Browning A-Bolt stainless stalker in 7mm Rem Mag and it has done everything I've asked of it for the last 5 years I've taken 4 bull elk, 4 mule deer bucks, 4 whitetail bucks, 2 antelope and over a dozen hogs with it without any problems. Shots have been from 50 to 300 yards. If I had it to do over again I would pick the .300 WSM for the shorter length as my 26" barrel end up getting caught in low hanging tree branches occasionally.
Pick the rifle that fits you. Tikka is good, Browning, Howa and Savage are too.
That's my 2 cents. Nathan
