Hi all. I just found this forum. Glad to see there's a place for us Handi enthusiasts to gather.
Anyhow, to the point. I've been interested in getting a 17 centerfire, and the Handi is a great platform. But since NEF doesn't make one, I did a little homework and an idea struck me. Please bear in mind I know nothing about gunsmithing, nor anything about the design of a rifle chamber.
So here it is. Using a Handi in 223, have a 17 caliber barrel liner installed and get the chamber reworked to fit the 17-223 wildcat cartridge. It sounds like it would work, assuming the barrel liner can be fit back far enough into the existing chamber and there is material enough on the liner to make reaming out the new chamber possible. I don't know for certain, but I would guess that the 17/223 matches the 223's dimensions behind the shoulder.
So what do you think? Is this a viable solution?
The possible downsides as I see them: I might have proposed an overly complex operation here, and it can be done more easily in another fashion. Furthermore, I don't know if the barrel liners (since I find them only for rimfires) can withstand the higher pressures and velocities of a centerfire round. I'm also suspicious that it might be pretty hard to get an accurate rifle this way.
Thanks for your input.
Dan
