The 25/20 WCF is one of my favorite rounds. When loaded down a bit it still works very good on small game that you want some of it left to eat.
I had a custom S&W "K" frame revolver built in 25/20 WCF long ago and it has been a joy to own.
Now, if you want cheap, you can swage your own bullets useing spent shotgun primers for the jacket. I do this sometimes just for fun... I swage them into a "Keith" style SWC bullet like the one loaded, of the three in the pict... They really work well!
