All the things said before.
Like the 308 offerings, 243s should all be relatively good. Tikka, Weatherby, Savage/Axis, Reminton, Browning and many many more.
If you like to tinker or like the idea that you can, Savage/Axis or a Rem 783.
If you are a take it as it came, almost anything.
I prefer Weatherby which would mean a Vanguad 2 for you but that's the rub. So many so many. So hard to choose.
My decision tree includes:
American owned company.
American made.
Ferners get some consideration for quality but... LOL
Try putting 243 into Gun Genie on Gallery of Guns. At the moment there are 90 offerings in stock. So much fun to shop.......
