I know this has been done, than done again, but I'd love to see them try again but using these methods.

The ice bullets all melted from the hot air, they also clearly showed un-burned gun power.

The fact that there was un-burned gunpowered says that the ice probably through melting or shattering from the force wasn't creating a seal in the chamber like normal bullets do.

Why didn't they try to make a Sabo for the ice bullet like in the chicken gun? One to create the proper seal for greater firing force, and protecting the bullet from the hot gases till after it left the chamber.

I'd also could say, couldn't they have made a bigger ice bullet? One that exactly fits to the chamber and I supose longer. The more mass, the less likely it is that the exploding heat from the powder will completely vaporize or break it.

How about something other than water for the ice bullet. Surely there are a ton things you can mix with water to make it stronger as ice. The point of the ice bullet is that it melts after its shot, who cares if its not pure water.

Just my idea's.
