I now have both, 280 and 280 AI. The 280 is a stock Win 70 FWT, and it just loves 140 gr. pills. 22" bbl ( I did have the crown re-cut) and it is fast handling, good in brush. I had the AI built with an 8.5 twist 5R 25" to shoot heavier bullets and monos. Working on a load now with Hammers. I wanted a little more punch too. If you want it, get it. The standard worked fine and was very accurate for a factory rifle - luck. It's a nice backup to have, but if I could only have one, it would be the AI. As another poster said, for hunting most game, I doubt the animal would know the difference.
