I'm super happy with my Weatherby Vanguard/Howa 1500, plus there enough chassis options and the aftermarket is growing quite a bit for these rifles so thats another great option as well!
EDIT: I always forget to give a shoutout for the one I haven't tried yet but I plan on it. The Ruger American Predator in 223/5.56 is a great choice and kind of my preference as it has a 1:8 twist which can handle some pretty heavy bullets. My biggest beef/I like it all at the same time is the AR-15 magaiznes now. I have lots of AR-15 magazine but I want to shoot heavy and the magazines can limit the design of the bullet. Its kind of a give and take with that rifle but it specs nice, wish the countour was a bit heavier on the barrel as well.
