Last I heard Mr. Echols used Burgess BM on his legend rifles. Mr Burgess understood that correct box geometry made for a better feeding rife and prefered an integral box design over the one size fits all approch. If I commisoned such a rifle I would know what I wanted so there would never be a need to go from a .30-06 to a .375H&H. It just wouldn't be an issue.
Everything has it's place and on a topflight custom rifle a Sound Metal Products, Blackburn or Sunnyhill would always get the nod over any steel floorplate sheetmetal box design for my rifle if it's an option. Sometimes it's not an option though. I've used Williams products before and like them. But, like I said everything has it's place.
