Wow, every place I could think of is out of stock. You could try calling Hornady directly, they may sell you one but it'll cost more than a retailer would. I think if you have a piece of brass they can make you one. I've heard of them doing that for wildcats although I've never done it.
If no luck with them PM me, I have one you can borrow for a couple weeks if you need to measure distance to lands in your rifle. Just mail it back.
