There are many good choices out there, but the 280AI is one of those rounds that I would consider nearly perfect.
That is ...if you're into headstamps!
Considering that what you want to do can be done nicely with a 308.
That is...if you're into bullets!
But if you really don't like recoil get a 7-08, 7-08AI or a Creedmore, and spend a few long nights on
JBM.
But whatever you choose, I'd be more concerned with things that really do matter...like bullets, mag length, optics, etc...headstamps not so much.
