First, if you shoot more than a little choke tubes will come loose. Unless you neglect them to the point they lock-up. Seen it happen on the best, so doubtful that Remington will be immune. Checking them on a regular basis should be second nature, especially for one who shoots a ton of trap, skeet and sporting clays. Surprising a HSI should find that, well surprising.
Thinking you should take you own advise to the newbie's?
I'm a hunter safety instructor, and I have a choke tube that was destroyed because it was loose in the barrel. I use it as an example, passing it around the class, as to what can happen if the choke tube isn't screwed in all the way.
Sounds like you have a lemon and deservedly so.
