I was looking for the exact same thing about 6 months ago. I bought a Howa 1500 .25-06 barreled action for a little under $400 and put it in a Hogue stock with the aluminum bedding block. If I had i to do over again I wouldnt change anything. It shoots great, fits me, and cosistently shoots sub-MOA groups with factory ammo. Another good option is the T/C Venture.
Never owned a Mossberg rifle, but IMO they are better off sticking to shotguns.
