So, I walked into a favorite toy shop the other day, and the owner handed me a nice little Winchester Model 1892 carbine. Made in 1928. Chambered for 25-20.   I had no idea how hard it would be to find 25-20 ammo. I found one box online for about $70 for 50 rounds. On top of that, it looks like Starline does not make the brass.   So.   I have lots of 32-20 brass.   Has anybody ever made 25-20 brass from 32-20 brass? I know it can be done, just want to know
