OK after reading first post I went to Gunbroker and looked for myself. This is getting crazy. I don't want to go conspiracy theory here but I can not see people hording 410 and 28 gauge shotshells. I just bought a Rizzini RB Deluxe in 28 gauge a week ago and found thorugh a source I have used before some 28 bore shells shipped at $10 a box.
They had no 12's, 20's or 410 shells left.
I was looking at a Rizzini 410 side by side but no longer am since you can not find shells for it.
