If you liked the ergenomics of the Senderos then possibly look into the Remington 700 police line. They make a Remington 700 LTR (20" barrel) 300 RSAUM. I would think this would settle your need for a light weight rifle that is capable of sub moa accuracy not to mention I find my LTR to be my favorite rifle. Its easy to bring up free handed and capable of being fired off hand if needed.
They dont show up too often but there was one here at one time.
