243 vs ?? for wife's hunting rifle?

[Mach2]

6.5mm creedmoor is very similar to a 260.
243 is 6mm. Less boom than 260
No one has recommended the 6mm yet I have talked with shooters who prefer the 6mm far better than the .243
BTW 6mm is .244

By 6mm is it safe to guess that you mean the "6mm Remington"?

Unless you AI the 6-Rem it just doesn't have enough over the 243 to justify it, and you are stepping up powder capacity over the 243 if you do go AI and thus adding recoil, plus 6-Rem brass can be tougher to find and if you seat longer bullets like 115 Bergers it may not fit in the mag of the SA the OP is using.

Literally 6.0mm = .236". In the firearms world however we use .243" as the 6mm diameter projectile size. Now the 6-Rem was also called the .244. Remington switched the name to try and boost sales when it revamped its rifles with the faster 1-10" twist over the 1-12" they were first released with.
