To everyone that suggested a new stock with the same action and barrel : Excellent idea and one that I did not think of. However, we (I must include myself) are excited about a new gun with new features and new possibilities.
I do not see him shooting 600 yards and beyond so there goes one of the advantages of of 6.5.
As far as handloading, he says he is interested and wants to learn. That could all change quickly so I'm thinking that the one with a lot of factory offerings would be the smarter choice. But I think that is a wash. I did not realize the 6.5 had so many factory offerings.
So you all confirmed what I thought all along. I will wait to see which rifle he chooses and pick one of those three calibers that is offered in that rifle.
Thank you
