Thanks for the update, Steve. Not sure why the .32-20 wasn't performing. The usual answer, assuming no dings on the muzzle crown, is that the bore specs don't match the bullet specs. When they used black powder and soft lead bullets in these "combination calibers," the small differences in specs (sometimes not so small in .44WCF and .38WCF) didn't matter so much--the bore and the bullet "sized each other" for lack of a better expression. With jackets and smokeless, they do matter.
And it ain't a target revolver, either. (But it's sure a keeper for pretty--nicest nickel I've seen outside of a museum!).
I like the combination of a K-frame 2" .38 and wadcutters. Up close and personal, it is very adequate, even "without a barrel." I have a 2" Model 64 that shoots as well as I can hold it; it was surplused by the NYS Dept. of Corrections some years ago. I don't think they even took it out of the box.....
