Sorry for Hijacking the other thread, I will start this over again new. There is continued intrest in chamber adaptors or inserts, I think an adaptor is only in the chamber while the insert contains a chamber and barrel. This is an insert to convert a 20 gauge shotgun to a 32 ACP gun. I did this as cheap and fast as I could think to do, I used a piece of 303 British barrel because they are avaliable cheap and they also take less machining because they are close to the right diameter (OD). I use a piece of cut off 410 barrel to build up the breach end because it is easy to do and takes a lot less machining than turning down the full length of a fatter barrel just so you can have a rim on the adaptor. I gave it about a .003 interference fit and just pounded it on. I did silver it at the breach end, but if I were to do this again I could eleminate the silver by leaving a very slight sholder on the insert at the breach end and driving the sleeve on from the front. After that I just turned the breach end to look like a 20 gauge shotgun shell, cut the chamber, made a little relief cut so the empty could be extracted and was basically done with it. I did cut a V groove inthe muzzel end for an O ring to locage the muzzel end in the shotgun barrel, it is just a nice tight slide in fit. Entire process took me about 3 1/2 hours, but if I were doing three at a time it would probably only have taken 5 hours total. All this could be done on a very small cheap lathe, all you need is a steady rest, the extractor cut could be done with a little skill and a Dremmel tool. I thik this is probably a good product for someone here to produce, I think they could be made up for about cost of less than $10.00 each, so what ever you can get above that is good profit. Good luck, below are some pictures, I think you can figure out how the fine points were done. The chambered picture is in my Savage 24, I don't have a 20 gauge H&R. The adaptor is in the classified adds. Larry
