In the past couple of years, however, I have discovered what seems to be a "free lunch" alternative. The Benchmaster and Caldwell Lead Sled shooting rests allow the shooter to fire very heavy calibers without the "ouch" factor
Excellent point Roskoe. I would also add the Tite Group Series of benchrests to that group. The rests are about 13lbs..
