I read all the information on that site and all I can say is that its pretty much a 22 CHeetah. Which is still faster than the swift. I think it would be a good round to have for dual purpose. They seem to have good experiences with it on deer and I have seen good things happen with the swift on deer alone. I think it might be one I would build a little later, fast and flat is what I like.
I have a 22/284 with a 30" barrel and 8 twist that shoots very well also.
A few years ago at a shoot out we had here in PA, two shots in a row penitrated a 5" diameter hard wood bowling pin with the 80 gr Sierra bullet. Had many witnesses that didn't believe it until they saw it happen.
