Flying10. I would not expect it as often in the UK, but in the US, it is pretty common for those with little to limited knowledge of something gun related to “make it up as they go”. Can’t tell you how many times guys have given me a cock and bull story just to either, A: Make themselves sound knowledgeable, or B: Make the product more interesting.
I always prefer to say “I just don’t know” rather than try and sell a story with a product.
