Removing the tank - Interesting thing ...
Interesting thing happened last weekend while I was removing the canister from my marker. My marker was more or less level (I've since learned that I should hold it pointing up) while I began unscrewing the canister. About 1/2 turn out I heard the canister disengage, and at the same time (here's the funny/strange part) my hopper popped open and about 5-6 balls bounced out of it. There were only a few balls in it, so I doubt the fact that I jumped when the canister farted caused enough force for the balls to push the hopper door open. It was almost as if there was some back-pressure causing it? Is there a way to explain what happened?
I have not since assembled the marker, as I have not had time to play with it.
