Crosman 111 bulk filling CO2

[Benelli B76]

For my other CO2 guns I have to transfer from fire extinguisher to bottles with different fittings...

that's often easier especially if you haven't a degasser to chill the tube before filling so gravity aids in getting a liquid fill and what I do with my 112
I made a few 88g refillable bottles with on/off valves a few years ago and use one of those mostly as it's easy to increase temp difference by wrapping warm wet cloth around it
