Brittany Man,
Your first answer is a good one. While I don't feel the need or desire for such, I can get my head around someone maybe wanting that. But, the deal with the 20 ga. shell in the 12 is more of a stretch, IMHO. People spending money to protect themselves from their own carelessness has always been a foreign concept to me.
Thank you for the reply, SRH
Stan,
I don't think the 20 ga shell in a 12 ga gun is a stretch at all. Accidents that I know about happen every few years w the 20 in a 12 & I know of a 28 ga in a 16 ga w/ the same violent result. I'm betting the people it happened to didn't consider themselves careless until after the incident.
I consider myself to be a very detail oriented person & every year after bird season ends I clean out the hunting vests my wife & I use, vacuuming out the game bags & pockets for feathers & debris & removing all empty & loaded hulls before I put them away for the season. Several times over the years I've later found a loaded round that got missed (usually in a vest that doesn't have shell loops in the pockets). Suppose that was a 20 ga shell that got fed into a 12 ga gun while you were reloading & marking a bird down or watching a dog bring a bird in & later a 12 ga shell got dropped on top of it.
My point is that accidents do happen & that is one reason I am not fond of rotating 20 ga guns w/12 ga guns & 28 ga guns w/ 16 ga guns & the 2" 12 ga is another & rather elegant way of avoiding the problem while having a gun of 20 ga weight.
On the sizing issue I really do find a 20ga SxS w/a splinter forend too thin in the left hand & a beavertail forend sort of defeats the purpose of of downsizing to a 20 ga.
