The vast majority of Burrard's testing was done with the standard British game load of 1 1/16oz #6 (british) size shot & was primarily for driven game shooting. He did do a limited amount with a 2 3/4" chambered gun firing 1¼oz of shot. He was "Surprised" to find there appeared to be no increase in shot string length. Due to high recommendations I purchased a copy of Brister's book. The only conclusions I could determine he arrived at was that Burrard was wrong in all he said, & if you wanted to reduce shot string you had to invest in WW SuperX/DoubleX (Winchester's highest priced shell). I then noted the book was published by Winchester Press. It now resides under about 6" of dust, but I use Burrard on a regular basis, as far as I'm concerned the best book on shotguns ever written. I realize that's contrary to many opinions here, but that's my opinion.
