Afraid I can't add anything useful to the conversation. Just bought a nice used Auto 5, 12 ga/3" - because I've always wanted one, even though I rarely use a shot gun - I just like guns - all sorts of them.
What I would like to ask, seeing as how you guys are already talking about it, is the use of steel shot. I'm confused and need some education on the subject. From my limited exposure to shot shell construction, there's a plastic/nylon compression cup, that contains the shot. It is my understanding that the shot stays inside this cup, all the way through the bore and once it's clear of the muzzle, the shot continues and the cup falls behind. If this is the case - wouldn't it make no difference if the shot was lead or steel, as it's not touching the bore anyhow and is contained inside this cup ? What is it I'm missing ? - or not understanding ? Thanks for reading.
