On this forum, and one other, I have posted information about a mechanical method for stretching brass cases enough to obtain a better chamber fit. I put myself in a predicament where that was necessary back when I bought a new batch of cases. Getting the horse back before the cart involved quite a bit of dinking around, but I managed (with the help of others) to devise a remedy.
Responses, here and elsewhere, lead me to believe that anybody can work himself into the same corner, and it does not require a 'sloppy' chamber (as recently opined) to do that.
If you want to know how I messed up, and what you may want be careful of, read this sticky...

In that sticky thread, I briefly mention a 'jig' that will keep everything in alignment.
The mention was brief because it was still being developed. I am now ready to try the prototype.
I could tell the whole story..mentioning all of the tools that have been made and abandoned, or made and modified...but that wouldn't be very enlightening for most of you. (I will, however, be glad to answer any questions on the subject.)
Suffice it to say that 'my tools' were designed to use on a 30-ton hydraulic shop press, and all of the later efforts have been to devise something that does not need a press like that.
I ran some threads aking for information about the beefiest reloading presses, and got some interesting replies. But, a 'universal' tool that can work on any reloading press seems to be wishful thinking.
The job simply requires a lot of push.
So........
Instead of telling a guy he needs a 30-ton shop press - or a Super-Ultra-Max Reloader's Special - the latest plan is to come up with a tool capable of providing a lot of push...that can be rented by anybody, for a day or two.
Enter the Porta Power tool set (aka 'The Jaws Of Life') which comes in 4-ton and 10-ton models.
The stretching jig I am about to put into service is of that type, and I will be using a 4-ton kit which I already own.
What I would ask from you guys is to check your local tool rental stores (where you can rent power tools, drain cleaning tools, and small landscaping equipment...among other things) and see if the Porta Power is generally available.
Porta Power is the name of the original tool, and there are other makers (these days) which build the same thing. So, you might find the same kind of tool under a different name.
Here's a page that shows some of the other brands...

If it is only a rarely found item in rental shops, I won't pursue the idea.
Thanks,
