I had exactly the same cartridges and did pick up the 280AI, especially for elk. Which to me means 160 plus grain bullets.

I have a Sako A7 25-06, and a Sako 85 30-06

Now I have a 280 AI and its more my first choice if I'm western hunting than anything else.

If I'm hunting thicker stuff where 300 is a long shot I just use my 260.
