Extractor cut details etc, for the MKII / 1905

[BrianLara400*]

Hi all,
does anyone have good photos, or (better yet) drawings of the standard extractor cut & feed ramps on the MkII /1905 ross's in .303? Mine has a "ringin" barrel that was very poorly fitted, which won't help at all for guidance when having the new replacement barrel fitted.

You have found a gunsmith prepared to cut the threads found on a Mk. II barrel? Let me know your email address, and I'll take some photos.

Big thanks to Tiriaq, these are the pics he took & they were a very big help in working out how to go about the feed ramp & extractor cut on a MkII barrel.

Figured it's worth posting them here, just in case they can serve as a reference to anyone else, attempting the same (I trawled all through google images, & couldn't find any decent pics):





Clearly the MkII on the left, with its 'gorgeous' 3 TPI thread & a MkIII on the right (for comparison)
there's detailed drawings available for the MkIII breaching details etc, but not so the MkII's.

Any CNC shop should be able to set up to cut the thread and the slots etc.

Superfluous to mention it I'm sure, but the breeching shoulder on the barrel should be left a bit long initially and then turned down to fit the particular action being used.
