I've owned and test-fired a number AI rifles from the .22 K-Hornet to .35 Whelen, and none had any trouble feeding (though one was admittedly a Ruger No. 1). A friend did have a famous gunsmith rebarrel a Remington Model 7 to 7mm-08 AI and it didn't feed worth a darn, though as I recall the gunsmith did fix it.
In my experience AI brass doesn't require much of any trimming. I'd wear out brass from my NULA .257 Roberts AI without ever trimming it. That in itself would b worth the price of admission on a prairie dog rifle.
