After ordering some cases from Starline last week, I decided to join the chorus of requests on their web page for them to offer cases for 25-20 or 218 bee. I asked if it wouldn't be feasible to further work their 32-20 cases to produce cases for the other calibers. After all isn't the 32-20 the cartridge from which the other two were originally descended?
the very next day I received an email from them explaining their reasons for not making and selling those cases. Since I thought their response would be of interest to all the fans of the 25-20, I requested permission to post it on the CBA forum.
We can hope that some day the manufacturing technology they use will improve and make it a good business decision for them to offer thes cases. But for now it looks like squeezing down 32-20 cases may be our best bet.
Thank you for your request. It is a very popular one. Unfortunately not one we plan on producing, at least not any time soon. A lot of times customers complain that it is a pain in the rear to form those calibers from .32-20, and say it would be a lot easier for them to just buy it from us finished. The problem with that is that as hard as it is to form 1 at a time for them, it is even harder to do it on a machine that runs 100 parts per minute! Plus, there are some slight differences in body diameter dimensions between the 25-20/Bee and the .32-20. While our .32-20 is in the middle of the tolerance for its body diameter, it is actually slightly bigger than the max diameter for the .25-20/Bee. This doesn't cause a problem in very many firearms, but since it isn't in spec, we would have to start from scratch on all of the dies and tooling anyway.
