The Compacts are fun to handle, but I haven't shot one. The light weight is going to mean more recoil, but in a .223 how bad can it be?
A lot of people disparage Ruger rifles, but I have yet to work with one that isn't a shooter. The only thing I do to them is float the barrel and work up good loads. Just picked up a Ruger M77 in .257 Rogerts last weekend. Floated the barrel this evening with sandpaper and a Magic Marker, poyurethaned the freshly exposed wood, and will put it back together tomorrow before heading to the range to sight it in. I fully expect this one will be a shooter, too.
My suggestion would be to get a full-size Ruger in .223, but if the Compact does it for you, go for it.
