Mike, Vall's rifle is somewhat unique. He will be along to explain it. My full-stocked 33A is in 9.3x57R.

Mike, my Type 33A has a .376" groove diameter, and the chamber uses .38-55 cases slightly shortened. I was told this makes it a 9.5 bore since a 9.3" would be smaller. The length is 47mm or 1.8" which also aligns with the 47R.
So as far as I can tell it's a 9.5x47R, but I have no idea what a 9.5x47R is that would take a .40-65 or .45-70 case and still be .375" and 1.8"? I've looked at Cartridges of the World before and seen the stubby little cartridge they show as 9.5x47R, but it's certainly not like mine. But mine isn't like the 9.3x47R either.

Vall,
I certainly can't argue with you about your own rifle, I have never even seen it, much less made a chamber cast. I noted a couple of these rifles on Simpson Ltd., but someone beat me to them, maybe you were one of them. The fact that you can use 38-55 cases means the cartridge is based on the British 360 case rather than the German Mauser Base case. Dixon (European Sporting Cartridges) lists a 9.5x47R with the Mauser Base cases, but not one under those based on the 360 based cases. There is, however, a 9.3x45R and also a 9.3x48R listed under 360 based cases, but only in the German form (German form chambers will not accept English form cases without resizing, even if the same nominal length). Indeed, 9.3 mm is smaller than 9.5mm, but old rifles were often found to use bullets with a smaller diameter than the groove diameter, depending on the black powder to obturate it to fit. The grooves were deeper, to (hopefully) provide room for black powder residue. Modern practice is to use a bullet the same diameter as the groove diameter. Also, old rifles often had chambers a little longer than the case length (maybe to provide room for residue?), and some had a neck and lead the same diameter, making the nominal case length hard to determine. I think your rifle could be chambered for 9.3x45R, 9.3x48R, or 9.3x57R, based on the variations discussed above, especially case form. Since I don't have a Husqvarna and HalfaDouble does, I suggest you PM him to solve the question. If you haven't made a chamber cast, it will be necessary to do so.

Yes, Vall's seems to be pretty unique. Mine is a pure 9.3x57R (360) with a .367 groove diameter. Vall and I had discussed his back when he started to shoot it. Anyway, what he worked out works well in his. Mine is also full stocked like his although I also had a half stock model which took the same ammo (since traded) and I also have a Husqvarna Cape in 16 ga x 9.3x57R (360) which takes the same ammo. The old caliber list for the Husqvarnas does list a 9.5 of some form to add to the confusion. My brass is made from 9.3x72R shortened and I use my 9.3x72 dies to resize it.

My particular Type 33A has caused a lot of head scratching for me, and others familiar with these guns too! So it's still a bit of a mystery! I even wondered if someone at Husqvarna put a standard 9.5 barrel on it, but reamed the chamber for a 9.3 instead?
I'm actually tickled to death that it is what it is as it shoots exceptionally well, and is so cheap, simple, and easy to make ammo for. But seems it will always be a mystery as to how it got the chamber it has.

HalfaDouble,
The next time you want to move a 9.3x57R, PM me, I have been "in the market" for one, for a while.

Vall,
Since you will keep using 1.8" cases, you might look at the new 360 Buckhammer cases. The Buckhammer is based on the 30-30 case with a .358" bullet and shortened to 1.8" to meet the case length requirements of the states that now allow straight case cartridges for hunting deer. You may only need to fireform and not trim them.

Thanks Mike!
With a lot of excess brass in things like .32 Win. Spl. that I don't own a gun for, plus a huge supply of .38-55 brass that I have a half dozen guns chambered in; my supply of brass is great. And since the .32 Win. Sol. is already too short to open up for my .38-55's and .32-40 rifles, it's easy to expand to .38-55 and then they're close enough that they don't need fire forming prior to loading. Just run them into my Lyman M die to expand, and then into my .38-55 die, and slightly trim to length.
The .360 Buckhammer brass is far too new to be an option as it's not been around long enough to find cheap brass. Plenty of cheap .32 Win. Spl. brass if I needed more, but I've probably got plenty to last anyone a lifetime.

Vall,
My situation is the opposite of yours, I form 8x57R/360, 8x58R S&S, and 6.5x58R S&S from original length (2.125-2.130") 38-55 cases (a little short but work if I seat the bullets "out") and I'm down to about 20 of them. Current 38-55 cases are the same length as 30-30 and I count them by the gallon instead of "each" and I don't own a 30-30 rifle.
Mike

I have a lot of brass I've kept from various rifles I don't own anymore, and no plans to own again. Most are based on the same rim as the .38-55 base rim, and most are shorter cases like .30-30, .32 Win. Spl., etc.
All my .38-55 cases and .32-40 cases are full length, so none of the modern short 2" stuff here. All but one of my single shots in .38-55 are Marlin Ballard rifles, so I wont use any modern brass in them.
