My granddaughter is 11 yr old and wants to deer hunt. She has only shot a bb gun before. Just based on recoil would either caliber be better. We have our own shooting range and I reload so ammo or practice is not a issue. I have a creed but would be willing (thanks grandma) to buy a 7mm as a maybe lighter weight option.
Since you already have the Creedmoor I'd go that route. Same situation comparing 6.5 Creedmoor / .260 / 6.5x55 vs 7mm-08 as with comparing 7mm-08 vs .308. If you have either one working well there's not a lot of point in buying the other. It's not 'til you start trying to do something neither is ideal for that you see much separation between them, for their best uses they're functionally equal.
One plus to the Creedmoor .. you can load light 100 grain partitions .. or even ballistic tips .. to modest speed and have a pretty solid killer without a lot of recoil.
