Was the Mallard cooked to temperature when it hit the ground?
Funny you guys cappin' on Kent Fasteel! I shoot it by the case-load since I have no reason for the Hevi now that I shoot the rice. I'm on my second case this season alone now as is my blind partner. We're shooting 3" 1-1/8oz #3's and we've got piles of dead birds including geese and no ammo failures or flaws. I'm shooting a Beretta 390 with either a Briley Lite Modified or Modified extended choke. My partner an Extrema. Out here, you'de be hard pressed to find a waterfowler that wasn't hunting it. I don't shoot at "tall" birds but then again, I wouldn't with any steel shot.
