..Hey Folks


My 400/350 rigby chambers fine with emty brass...but with .358cal bullet seated, it appears the caseneck is too thick, so it can`t chamber. Shall I turndown the caseneck so much it gets really thin, or should I order a chamberreamer custommade after my cartridge with bullet seated??

Slug the bore first, check the diameter of the bullet, and resize the bullets to match? Might only be .357 or .356...

Bare belastning det med tomme's denne måde ingen ændring er nødvendig, og tænk på de besparelser, vil du se. Ha Ha Cheers

Check your cases & bullets separately first with calipers or a micrometer to ensure they are correct ,

Now if the problem still exist Cast your chamber and figure out where the problem is BEFORE reaming or

cutting anything . JMO. BOL .

Is this using today's cheap-o Ryan & Easy Jet flights or the 793 AD standard? If by the later order me 1/2 dozen Wenches & some Pillage booty posthaste.....

Agree w/Doc, if the once fired brass chambers and the resulting reloads won't chamber then the issue is either the bullets (first guess) or the Dies. I would concentrate on the Bullets, then the Dies - I wouldn't concern myself with brass at the moment.

It's easier to change the Bits & Pieces surrounding the rifle such as Bullets, Dies & Brass than to have an altered chamber.....

what you should never never never do is defile a original rigby with a chamber reamer.

please slug the bores and make a chamber castor or ask the guy's who did the resturation work to help you.

you dont change the gun if you can help it, changing bullets or cases are the way to go.

Jens, have you got access to brass fired in this chamber?? If yes, the neck diameter of the fired brass will give you a good idea of the chamber internal neck diameter. Figure: fired brass diameter = neck diameter - .001", or so.

Alternatively, you can either have a chamber cast made, or, if you know the smith who chambered your barrel, ask him for the neck diameter of the reamer he used.

You then compare internal chamber neck diameter with loaded ammo neck diameter. For a caliber like yours, you'd expect loaded ammo neck diameter to be, maybe, about .005" below chamber neck diameter - for safe and reliable operation. This will also tell you whether the neck is where the problem in chambering loaded ammo lies.

Should it transpire that the chamber was cut for different brass than what you use, you have a couple of options. 1) you can get a neck reamer and ream out the chamber neck to be loaded ammo neck diameter + 0.005", or so. 2) Alternatively, you can turn case necks. But there is a limit to how much you can turn, even with necks thickened from a neck-down operation.

Alternatively: try different brass - if any is available to you?

Also, If you have brass fired in this chamber, see if a bullet will slip into the neck of the case.

If not then you will have to either enlarge the neck of your chamber, get thinner brass [in the neck], or get smaller diameter bullets.

Thanks Gents

I will have the bore slugged + a chambercast made aswell. Changing the original chamber would be a sin to this nice old gun.
It might end up with that the bore is .354cal like the 9x57mauser. I believe it was mauser that made action and barrel to Rigby, and I don`t think mauser would change to a .004 larger to an already excisting diameter.

Problem solved!!!!

The caseneck on the original Rigbys 400/350 and .350RimlessMagnum according to C.O.W are .380" my cartridges measures .388". I have a Rigby .350rimless here and it too measures .380"...leaving .011" in wallthickness only. That is very thin. Modern cartridges has atleast .015" wallthickness.
Cases will be returned to Herr Horneber.
I know it would be tempting to just ream the chamber in the neck area up a bit, because that will buy me a thicker wall = stronger brass.
