Ah, so you DID inherit them. Got it.
Ammunition is not hard to find if you know a few of the distributors.
I got a couple on the first try.
Kind of expensive, but not as high as boutique Bullet of the Month 9mms or such. I figure a box or two would be a long term supply. A friend refers to shooting such guns "on Ceremonial Occasions."
I am surprised to see the "modern" .32-20 Mike mentions.
There are more old guns than new in the caliber and I would not want the liability. Put some of those in a Spanish knockoff and you would have a recipe for disaster.
