I was cruising a local pawn shop today and found a M110 in 223. I can't seem to pass one of these up so it came home with me to add to the collection. What was different about this one is there is no mag cut out in the action and of course no mag. A shallow trough was milled out at the factory that goes about half way through the bottom of the action. You lay the catridge in the trough or slot. It is definitely a single shot rifle. I like the idea but haven't seen this before in a standard factory action. I'm pretty sure it's not some type of target action and it is a savage blued action. When I took everything apart I could tell the rifle had never been apart nor shot very much. The barrel was a savage 26" long 1-12 twist in a sporter profile. My question is how common are these type actions and are they really any better than a regular action with a mag? Not asking what it's worth as I'm not interested in selling it. Just want to know if I have something special here.

Thanks,,,,Floyd
