soda bottles aren;t that brittle when pressurized unlike pvc so it wouldn;t be that bad.

In this case, they were taken to relatively low pressure which is well within the limites of pressures at which such bottles are manufactured to:

I have personally tested the chamber above up to 90psi without any visible signs of stress, but I don't intend to use it above 60psi in the field. The tallest tree we shot this year (over 100ft) only required the use of 45psi pressure.

I really like the chamber on this thing.
And it has found a commercial use as well.
I am thinking of a chamber similar.
But with 2-liter bottles and pvc ball valves seperating them for multiple shot capability.
