"I am wondering why you are trying to size your cases for a chamber you do not have. Time and time again I have claimed my favorite cases are cases shot in trashy old chambers. I have purchased cases from firing ranges, one range would allow me to measure the length of the cases from the shoulder to the case head; again, I was only interested in cases that were ling from the shoulder to the case head. They charged me by the hundred but threw in an extra 10 for every hundred.
There is no manufacturer that sells cases to reloaders that know what they are doing; I do not want cases that will allow the bolt to close, I ant cases that will not allow the bolt to close. SO? When I start to size a case I am forced to reduce the length of the case from the shoulder to the head if the case (or as bumper say; bump the shoulder back), difference: I have to know when to quit sizing. .022" is a good number to start with.
A variety of cases: Manufacturers do not manufacturer cases with a variety of case rim thickness. If they did I would prefer using the case with the thickest rim. I do not want my rimmed case heads moving. That brings us back to the full length sizing of cases for a chamber you do not have. Increasing the length of the case from the shoulder to the case head can off set the length of the chamber with the case. That does not change the design as in the 30/30 head spaces off of the rim and that leads me to believe they had little interest in what happened the case in front of the rim 'or belt'.
The rim was designed to hold the case to the rear and the case body was designed to fill the chamber.

Mr. Guffey....
As you may know, I'm very new to all this (see my post count
) and trying to capture all I can from these threads, but above, in your 1st reply, are you suggesting that these cases he purchased may or may not be once fired cases, but they surely are not just stretched .022' but are rather cases that have been HAMMERED with heavy loads, and are best discarded and not used? To me, .022" of stretch seems excessive, if at all possible with a standard chamber??
Likewise with the original poster, just trying to get this all understood...
Thank you in advance.. eschafer
