More than one shot per fill? Either you have too much fuel, or it,s not mixed properly.
Can you draw a diagram of what your chamber looks like.
Also, how did you calculate the volume? Is you chamber long an thin that has pockets where gas can accumulate?

It sounds like you're using too much fuel. From what I can see you should be using ~17.5 mL of butane for that chamber size. Have you installed a chamber fan yet?

The fan does more than just air the chamber out, it helps get an even mix inside the chamber before you fire.
