We couldn't find it. It entered the roof near the edge, continued through the screen, and in to the ground outdoors. We did a lot of digging around, but ultimately were unable to recover the round.

The holes in the aluminum roof were round (ruling out a tumbling rifle round) and were definitely larger than .22 caliber. Most gun discharges on occasions like New Year's are handguns, so it could have been any number of handgun rounds in the .35-.40 caliber range. It wasn't large enough to have been 45ACP or .44 Mag. It could have been a .30 caliber rifle round, but given the estimated angle of entry, I would have assumed it would tumble by then. To leave such a clean entry/exit hole would seem unlikely for a tumbling rifle round.
