I have a friend that has a vast Thompson Center collection. He belongs to the big club devoted to this unique firearm. He has gotten me interested enough to own a few and I do think the accuracy is superior to just about any other "pistol" I have ever fired, they are single shots which makes them a little on the odd side for what most people are interested in. One of the things we talk about is cartridge shortage and in the Contender world 32-20 is one of the most sought after, it is the basis for a number of Thompson wildcats including the .218 Bee. 32-20 is in the family of irritating tender necked cartridges like .22 Hornet and 25-20, and one of the reasons fewer people today mess around with them because you can get superior results from common bargain basement calibers like .223/5.56.
From the perspective of being uncommon and as much work to produce as those more easily sold it makes sense that for as long as I can remember .22 Hornet has always been expensive to purchase outright, as well as 32-20. I had a .22 Hornet way back and a box of 50 Winchester ran $10, it was 50 rounds where most other rifle calibers were 20 to a box, if you factored that in it may not have been so expensive, it just hurt to plop down a ten dollar bill in order to shoot that rifle, before I started reloading. My grandmother reloaded that .22 Hornet with a Lee Loader, they lived way out.
