Jeez do I remember my first shotgun - a Ted Williams (Sears) 20 ga pump with a Pollychoke. What an abomination for a 12 year old! I remember one dove hunt where I twisted it so many times that I launched it (fortunately- or not - saw where it went). In a testimony to those unidentified engineers, the bloody thing screwed back on. No real difference with the swells who are constantly changing tubes, stock demensions, etc between misses. At least I was twelve.
