Hey Forty,
I have never tried them, but I looked mighty hard at them for a potential option for me Grand-da's .32 rimfire J.P. Lower pistol. Dixie sold a kit that used 22 primed cases and inserts to load your own rimfires. I imagine it is still pricey, but the more you shoot the more economical it would be.
Also, pictures my good man, we want to see them!.
