Did you do a build thread on the biggun?
No, I probably should have. Turned out complicated then I anticipated.

A filament snarl.
This is the second time the Bowden has plugged in the year or so I’ve been printing. I don’t know why it happens, but I suspect it’s related to times when I get the bed height wrong and plaster a thin sheet of filament to the bed.
Looks like you have a creality printer. Are you using the stock hotend? If so then I'd suggest you try the following:

That's just about exactly how I was assembling my hotend before I had the problem too. The difference was I left the nozzle about one turn loose, pressed the Bowden down right against the nozzle and then tightened the nozzle the last turn. Yes this works well except for one thing, you are relying on the pneumatic fitting to maintain a solid grip on the Bowden tube to ensure it remains pressed tightly against the nozzle. That is the weak link. You may not have experienced this failure yet and I hope you never do but many, many people with stock Creality hotends have. Doing the mod, which only requires a couple parts you can print yourself, removes this weak link from the equation. It uses the threads from the fitting to hold a section of Bowden tube against the nozzle. I trust threads way more than a few barbs. But that's just my opinion, you can do whatever you want.Actually no need for that part. Just remove the Bowden connector at the hot end and pull out the tube enough so that it will touch the nozzle just as you are tightening the last thread on the connector. That way it is pressed onto the nozzle. Mine is printing away with no leaks, a lot less than stock config.
Oh, and I am printing the last section of a Saturn V 1st stage.
Have a roll of TPU that I purchased for another project and thought I'd give it a go to make disposable ejection end caps. After a few adjustments on size, I got them fitting nicely. Way better than tape.

Disposable? So a pieces of plastic that wont be recovered? That might not make landowners too happy.Great idea!

Also printed a very nice fin jig. The design was done in Fusion360 and can be changed easily for any configuration. Took some time to print but well worth the results.
Masks for those on the front lines... they are sent to a clinic that adds fabric and elastic and then are sent to where they are needed.

Very nice! Have you considered posting the files anywhere?
