I picked up a Shooters Ridge gun rest last year and it works really well to soak up recoil during the sighting-in period.
However, as discussed when this question was last asked 2 weeks ago, a rest doesn't replace practice with, and fine tuning of, the rifle once you've finished with the sighting in.
And most rests, of any design, also tend to transmit your bad shooting habits. If your breathing wrong, squeezing the trigger wrong, pushing on the stock too much---whatever, it will throw off your results.
