Jon & Patronen -

I get all my measurements from The Handloaders Manual Of Cartridge Conversions, by John Donnelly. Donnelly did not measure or inspect all the cartridges he lists (one per page, 1054 pages), he copied reports from various sources, the principle one being Cartridges Of The World, which is where data on all three 30 cal cartridges commented on here were taken. The data in this book concerns the shell, not the load or bullet.

Personally, I believe the cartridge manufacturers and reamer manufacturers/distributors have, over the years, combined differently named cartridges that have dimensions within manufacturing tolerances under one name. (Or, conversely, mark the same reamer/cartridge with different marks).

A good example is that 24 minute angle addition to the 16º neck angle shown on that diagram. I seriously doubt that any manufacturer is going to hold to that exact dimension...

jonnyc - I have had too many C96 & M30 Mausers with beaten locking block abutments to even think of firing anything but a target [read: light] load in them...and then only with a good abutment...Here's an example of a mildly beaten abutment...
