Duty ammo for my carbine

[Caduceus]

But as I thought of it I have both my buis and optic zeroed at a hundred yds and used xm193. So I may be SOL. Unless POI for the ppt is within a quarter of inch difference at a hundred.

I doubt it. I ran a few flavors of ammo a while back and POI was within a few inches between them all. Not really sub MOA between different groups. Wouldnt be that hard to recalibrate, though practice ammo could get pricey.
