I get the “I want a new gun” itch, but I’d suggest you get to the bottom of accuracy issue with your 270 first. You say “ but I've treated it like a bush pig and accuracy is starting to waiver“. What does “ treating it like a bush pig” mean ?
As well as a recrown I’d suggest you look at your cleaning technique and methods. carbon or copper fouling will accumulate over time and cause accuracy problems. If left unaddressed will get worse over time and more rounds. What’s your cleaning regime? Try some good carbon and Cu solvents and/or bore paste or autosol before doing anything. You may find this fixes your accuracy problem in the 270.
Some other thoughts (you might have done some of this already?)
Howa is capable of good accurate rifles, but the stocks they often come with are not great, especially the Hogue stocks. Fine in the bush, but too “floppy” for longer range accurate shooting. This may also be source of accuracy issues. An investment in a good stiff stock, eg B&C, and a bedding job would be worth considering, especially for longer range shooting.
Is the 270 suppressed ? If not that would be my first investment
Optics, check that your bases and rings are torqued up correctly and not loose. What scope are you running ? If you can solve the accuracy issues with your 270, which might require a new stock and recrown, then you’ve got a rifle capable of 500-600 yards on deer provided you use the appropriate long range pills and the conditions and shooter are up to it. But depending on what current scope you have, you might want to upgrade to better scope for longer range shooting. Eg a quality 3-15 or 3-18x scope. The 270 could then be your longer range set up.
Reloading - really is the best answer for LR rifles. Gives you the best options for pills and powder/load to tweak best accuracy from your rifle.
Then for bush pig look at 308 or 708 with 16 or 18in bbl.
