    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping.  In the USA shipping is $5.00 for media mail.

    Sorry nothing there. Did multiple searches even using 280 nitro express (Rimless) so if it is on the web some place I cannot find it. I have the bible but some of the numbers are a little blurry for cartridge dimensions. The book also doesn't show chamber dimensions.

    This is a little clearer than the book. More generic measurements though.

    Probably just end up using cerrosafe in the chamber and go from there.

    Try the Canadianicon Patent Office or maybe the U.S. Patent Office.

    Excellent! Just what I needed.

    Do you have a source for the files you provided? I wouldn't mind purchasing a copy.

    Found the website. Good info there for old calibers!

    I've always found Commission Internationale Permanente (CIP) very useful - and its free. The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) charges for the service.

    "...(SAAMI) charges for the service..." SAAMI specs are on-line for free. Click on 'Technical Information' then 'Cartridge and Chamber Drawings, then Rifle, etc. Opens as a .pdf. Right click and print.
    The .280 Ross probably isn't there as that though. Might be as the .280 Nitro Express. Didn't look.

    Spelling and Grammar count!
