I have a feeling this whole thing is going to be a flop. Ammo is not as cheap as they claimed it was going to be and it's pretty damn close to 17hmr and some of those ones. As well, there's way better gun selection for existing rimfires (I know that's not really a fair comparison but it is the truth). You'll probably be able to reload some of the smaller centerfires for what the ammo is going to end up costing, and get way better performance. And for the price comparison vs .22lr ammunition I will just stick to switching between the .22 and .204.
That being said when it eventually gets worked out and comes out in a heavy barrel I will probably buy one.
