Hallo Daryl,
Thank you for your response

I have no doubt in what you are saying about the experience you have with this caliber. There could be many reasons for my tight chamber or your large one.
I just try to bring some light into it - but unfortunately this does not mean I have the full scope.

To understand when the Husqvarna rifles were produced we have a look at the following webside:

http://www.skydevaaben.com/allhvamodels/info.xml

Model 46 produced between 1927 – 1937
Model 146 produced between 1937 – 1941
Modell 46A produced between 1942 - 1945

You are referring to CIP a couple of times. CIP was as you may know, founded in Brussel in July the 15, 1914, just a month before World War I starts. Belgium, France, Italy and Germany had originally sign in.
Belgium ratified it first in May the 15, 1925, followed by France in May the 14, 1926, Germany August the 12, 1927 and Italy in 1929.
If I understand it correctly, at the beginning the meaning of the CIP was just to except the others proof regulation and proof signs.
As John Speed is showing in his excellent book “Original Oberndorf Sporting Rifles” on page 274 and 275 the cartridge (9,3x57) was not listed in the German Arms and Ammunition Manufactors Association agreement on standard dimensions on July the 23, 1926, see Mauser factory chart No. 40138.

The German proof law of July the 7, 1939 ruled also the max cartridge dimensions and from this time we should have quality data but even the “Schiesstechnisches Handbuch fuer Jaeger und Schuetzen” of RWS, printed in 1940 still did not show the 9,3 x 57 as normalized (see page 44) although RWS load it with one load, No 60 at that time.
On July the 1, 1969 the CIP rules where enlarged and include ammunition control (pressure and measurement) as well as method of pressure measuring and also a list of cartridges and calibers with dimensions and other things.

I refer in my former mail that dimensions were available 40 years ago in the Dritte Verordnung zum Waffengesetz 1976, which you could translate as the third act to gun law of 1976.
This gives an overview what the CIP data should have been at the time when the CIP rules where enlarged in 1969 if the cartridges had been listed then.

However the rifles where manufactured long before CIP could have any influence in the dimensions and even today neither Sweden nor Norway belongs to the 14 States who are members of CIP.

Last but not least I would share with you a link to CIP, where the 9,3 x 57 is listed since May 2007 as you can see:

Do you have a Model 46, 146 or 46A? Maybe the time of manufactoring give us some additional answers.
As I said mine is a M146
