In my overconfident youth I used to reload 32 Rimfire. I used a homemade tool to clean the rim and partially remove the firing pin indentation. An old chemistry book I found at the library provided instructions on a priming compound that was very stable when liquid but did not require much of a blow to detonate when dry. FFFG powder and a press fit cast bullet would get me 2 -3 reloads out of a case. When my dad found out what I was doing he took the rifle, an old Stevens Favorite, to a machinist friend of his who converted it to 32 Long. A wise decision on my dads part I must say. I’d never try 22 RF and would not reload 32 RF again unless I was really really desperate.
