Trying to decide on a new rifle for my daughter and debating between a 308 and a 6.5 Creedmoor. Looking at some online recoil calculators there doesn't seem there is a whole lot of difference in a 143g 6.5 moving @2700 fps and a mild loaded 150g 308 @the same 2700 fps. Same with the 123g 6.5 and a handloaded 130g 308. Can anybody who has experience with the 6.5 shed some light on this for me. Maybe I'm wrong but I don't see where the 6.5 will be any better than the 308. She is almost 11 yr old and big and stout for her age.

Thanks
