.223/5.56 bolt varmint rifle

[thumbs]

I know Mossberg makes the MVP(I think) that will take both cartridges. Is there anyone else that makes a varmint rifle that will take both? I have a bunch of 5.56 and some .223 and I would like to use both in the same rifle. Without worry about a 5.56 in a .223 wether it is a problem or not.

thanks
