Since I am building a .500 jeffery for mr.rigby, and has not built any in this caliber before, what is the correct reamer to order, and from where? Ditto for the dies?

kinda "doesn't matter" as long as the dies and reamer are cut to the same spec.

Hehe, yea, ok, new question, what are THE specs to order for? The most common used today?

Get in touch with Arthur Smith of Arms Restoration Services in England, Arthur makes cut barrels upto 2 bore and also supplies reamers.

My own reamer and headspace gauges to CIP spec came from him as did my Jeffery .500 barrel his contact nuumber is Tel/fax 01206 272354.

This chamber reamer is conducive to use with modern Kynamco made Kynoch ammo.

hope this helps

Bent,

Note that the reamer currently used by Heym for their .500 Jeff rifles is not conducive to using Kynoch (CIP standard) ammo, and that Romney ammo is made to a different shoulder angle than Kynoch.

Triebel make dies, reamers and no go gauges for both chamberings (Jeffery and Schuler) Very important to the issue is that the 500 Jeffery is not the same case as the Schuler 12.7 (aka 500 Jeffery) So with this in mind we have already two seperate but almost identical chambers and dies. Most popular loading and cartridge publications in error perpetuate the notion that the Schuler = 500 Jeffery. Here is where it differs: So what this means is that the CIP spec 500 Jeffery should fit into a Schuler chamber but not the other way around. So as not to think the CIP spec came from some thumb suck. It was derived from the original Kynoch drawings of the 500 Jeffery. It was also then correlated to the chamber casting of an original 500 Jeffery rifle. A copy of the original 500 Jeffery cartridge spec. A copy of an early version of the Schuler:

So could you not shoot either in the Schuler chambered rifle or am I wrong? As usual I am thinking about worse case scenarios here.

The 1928 Kynoch and 1997 Romey 500 Jeffery ammo should work in the 1940 RWS Schuler, though not a perfectly reliable fit for a DGR where a possible hangfire or sluggishness on bolt closure is to be avoided like the plague.

Now there is a fourth chamber supposed to be the new CIP standard, 1998 Kynamco with 25 degree 16 minute shoulder. Thanks to Jonathan Tomlinson for pointing that out.

They all seem to have the same neck-1/shoulder meeting point, or close to it.

You ought to be able to chamber all of them in the 1998 Kynamco, but non spec ammo in a DGR, zeese eese verboten.

Pick your chamber and dies to match and fire form your brass once for reloading if all is not a perfect match, so they say.
