Safarischorch:

If your only source of info is from Hatari times then you are behind on the 500 Jeffery and 500 Schuler.

The original Kynoch drawings and chamber casting of the 500 Jeffery differ to the original 500 Schuler chamber and I will show you how they differ.

There is no doubt that Jefferey's 500 was a Schuler crib but when Jeffery asked Mauser to chamber their 21 rifles and the 3 built for Gibbs their chamber dimensions were different to the Schuler.

So here are the critical dimensions: look at the date on these drawings: This is also the spec accepted by CIP for the 500 Jeffery.

this is an original Schuler drawing:

This is the critical dimensions drawings showing why CIP accepted the 500 Jeffery as different to the Schuler.

So if in doubt:

Here is rifle number 5 of 21 delivered on 9 May 1928 from H leonard & co to Jeffery then sold to Abercrombie & fitch of 7th Ave New york, now residing in my safe

Here is one of the original Fletcher Jamieson 500 Jeffery rounds loaded by Kynoch for Fletcher, he later pulled the bullets with a plier and the marks can be seen on the bullet. This ammo was specially made for the last Jeffery rifle built by Leonard for Jeffery.

This is the first newly made 500 Jeffery ammo made for the 50th commemoration of Land Rover vehicles for the special rifles made to commemorate Land Rover.

It is this ammo batch made to spec from chamber castings from a 500 Jeffery rifle known as the Van der Bijl rifle out of Rhodesia that prompted the reseach that lead to CIP accepting the CIP spec for the Schuler and the 500 Jeffery as being different.
