I just don't see how this is going to catch on. It's basically a non heeled .22 L.R. At 1,725 FPS it's not much faster than a lot of the high velocity .22 L.R. rounds that are available. Ammo has got to be more expensive. The bullet has a non standard diameter of .2105.
That's not going to do anything for its popularity or performance. It looks to be another solution looking for a problem. The .17 HMR has caught on somewhat. But Winchesters version of that failed. I wish it luck, but I'm afraid in 5 or 10 years it will end up like the 5 MM Remington Rimfire Magnum
There are a lot of those rifles in search of ammunition. And it's expensive when you find it. We'll see what happens.
