I just wanted to comment on the 25/20WCF cartridge when used in a revolver. I have a S&W "K" frame chambered in 25/20,
The biggest problem is, is getting a variety of bullets that will work in the short chamber of a revolver. I finally designed a "Keith" style 25 cal. bullet for mine, that i swage, sometimes using a spent shotshell primer for the jacket, (not pictured)
And they work very well on the small game i've used them on.
