I read somewhere about the 327 federal magnum necked down to 20 caliber. Lost fewer cases than using the 357 case. Don’t know why the 20 caliber/5mm isn’t more popular than it is in a small case.
That sounds interesting. Any word on performance?
I believe I read about it over on saubier.com. I did a quick google search but that didn’t turn up what I was looking for.
