I thought that the bullets just physically disrupted the bonds between the blocks- it didn't blow up the actual blocks themselves.

Yes, do you remember when onboard Thor's ship, O'Neill shot a Replicator and it rebuilt itself, why didn't this ever occur again?

The way I see it is if your not watching the movie in slow motion or any of the episodes with them in it how do we really know if they aren't reforming. There is alot of shooting and moving going on that they could in fact be putting themselves back together or they would have aleast made a very very minor dent in numbers.

Bingo!
