Rabbit;
Burrard discusses this in Vol II under the heading; Pressure/Length of Cartridge, beginning on page 152 & ending page 155, much too long for quoting here. In essence as I said he discusses the two different situations of a "True 2 3/4" cartridge & a 2½" load put up in a 2 3/4" case as entirely seperate entites. Thoms did not make this distiction when quoting him but treated his statements on the True 2 3/4" load as applying across the board.
Whether this was intentional or merely lack of complete research, is really immaterial as far as I'm concerned, it simply fails to inspire confidence in a man of his supposed position who either doesn't know whereof he "Quotes" or intentionally misquotes.
Fact is it was sttled in GB about 1938 & re-affirmed around 1946 (After the War) that if the regular 2½" load was put up in a paper case of 2 3/4" length & closed with a fold crimp, giving a "loaded" cartridge of normal length for the 2½" chamber both pressure, ballistics & pattern were essentially normal. there really was little left for Garwood to investigate in the matter, he simply needed to "Study Burrard". His findings did of course confirm what had already been Confirmed as well as did Bell's all these years later, except I believe he got the same results using plastic cases.
