Default 260 Rem vs. 260 AI ???

OK, I've narrowed down my cartridge choices to these two for my rifle build.
I have the short action Remmy action on the way.
One thought I had was concerning the short action. This will obviously limit my seating depth for the 140 gr.+- bullets that I plan on useing for this rifle.

1)Should I have considered a long action for this cartridge????

I could load one @ a time if they are too long for magazine, that would not bother me, since it will be a bench gun only. 2)My thinking was that a short action would be stiffer, therefore better than a long action???

3)Will I gain much in terms of velocity with the AI?

4)Is the AI cartridge inherently more accurate?

5)Where can I find AI reloading dies?

6)As far as full length sizer vs. neck sizer, which one should I use?

I read that the 260 AI is the ballistic twin to the 6.5-284 but the AI case is alot more efficient. In a couple of my loading manuals they list the 260 Remington velocities near that of the 6.5-284, within 40-80 fps using same bullet. If that is all I gain I don't think it would be worth the hastle to fireform.

Set me straight here fellas, Thank you, Hawkeye
