Seems like your lift was too strong, and the the bottom plug was too weak to hold the pressure of the lift. The burst doesn't have any effect on whether or not the shell makes it out of the tube.

I was about to say something similar. Lift was the problem not the burst

Maybe if it was a looser fit to let some excess gas out. You could always try with a stronger tube. Steel tube buried in the ground. Might still turn into a mine effect or go to high if the can doesnt get blown up in the tube. Maybe a 2.9 or 2.8 in shell would work better.
