Back in the 50's there was a particular experimental ammo round that never caught on, the .222-17. Later, a 17 did come out which we all see today; what I am looking for is not quite the same. The brass had to be hand fashioned and there was not a lot of it made, but its out there. I have one round. Does anyone have any of this in any amount that they would like to get rid of all or some of??

I'd never heard of it before so I Googled it... this was interesting: http://www.6mmbr.com/17wildcats.html

I think that you are talking about the cartridge more commonly referred to as the 17-222. Several wildcatters experimented with the 222 cases and the 223 cases. There are several different wildcats that are 17 calibers based off the 222 cartridge. The simplest form of the cartridge is just the 222 necked down to 17. If you are looking for that, I would suggest just fireforming some brass. You can pick up some 222 brass easy enough and firerorm once and then start to reload the brass. just an idea.

That would be good except he needs to make it smaller, not larger. Fireforming blows things out larger. Instead, this will require sizing it down and probably inside reaming the neck to remove excess brass. You might be able to take a .222 neck bushing type sizing die and use the smallest .22 bushing then the smallest .204 bushing, then a .17 bushing?

Unclenick, thanks for setting that straight. I guess I had a huge brain fart and for some reason got in my head that the cartridge needed to be blown out. Using the smallest 22 bushing then the 20 and then the 17 would probably work. Just remember to use plenty of lube when you are sizing the cartridge down.
