IC: I hate to be a bucket of cold water,but me personally, I could never get very enthused about the whole AI thing. I say that knowing full well that a lot of very experienced guys on here love them.But really,if you want more velocity than a 7x57 gives, just rechamber to 280 Remington.Brass is common,and you don't have to fire form it.

Besides,what's wrong with the 7x57 the way it is,like Al Biesen indicated?




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
