I took your advice Marlin93 and I had the chambers and bore cast. Three of the four are 9.3x57R (.365-.367 bore) and one is a 8x42R. Now to find brass or make brass for the 8x42R.

8x42r used a mauser based cartridge. hard to find something that will headspace off the rim in such cases. you might have to size from donor to headspace off of shoulder. 8mm lebel might be a suitable donor.
I was wondering if there is a diagram/spec sheet on that cartridge. Maybe reform 8x57R?
Old thread but since I have a 33A in 9.3x57R that I am working up I thought I would post some info. I am using cut down 9.3x72 cases. NOE molds also has a mold that should work. It's a .362 mold I think but mine drop at .365
The 9.3x47R case is 2.25 inches long so 38-55 is gonna come up short. I tried using some 38-55 and got some severe leading. Wound up finding some Norma 9.3 x 74R and trimming to correct length. Now I need to turn the necks as they are too thick for a .367 bullet.
Being chambered for a BP round (basically the Swede version of 360 Nitro Exp) I was surprised at how high the rifling is.
I've worked with a couple Husky's and I had to jump through some hoops to get both of them to shoot cast bullets. However....brother was it worth it!!!

I've got an old JP Sauer stalking rifle in 9.3x57R 360, and I've been using starline original length 38-55 brass with the rim diameter slightly decreased. I load smokeless loads for about 1200FPS using a paper patched 155 grain .358 bullet (patched up to .368 for my .366 bore). It's an excellent shooter with that load, and it doesn't beat me, or the 5 lb rifle up! I'm only punching paper, so I'm not interested in hotrodding it.
I spent a lot of time and energy making "correct" brass, including making some from such things as 30-06, 30-40, and .303 british brass. I also bought some correct headstamp brass for $3.50 a piece. The best shooting of the bunch for me is the 38-55 brass.

I'm so very happy my type 33A is not the smaller diameter 9.3! Since mine is the 9.5 and uses the .38-55 cases it's cheap and easy to load for. And extremely accurate, with a perfect bore.

Is that a slick that you patched? Sure would like to hear some details on your load!

It's a bullet from a group buy mold that Mihec ran a few years ago for subsonic 9mm. I don't have my notes handy, but I'll try to dig them out soon.

A collection of Swedish rollers... oh!!!!! Be still my heart!

Like to hear about your experience sir!
Briefly; A Model 46 in 9.3 X 57 needed what for me at the time was a lot of work on the brass. Big groove diameter, tight throat.
My Husy roller in 8 X 56 wasn't bad. Large groove diameter but fortunately not a tight throat. Had to turn the rims and take a little off the head.
I might ought to start a different thread.
A friend is working with a roller in 9.3 X 57R and he's run into some difficulties with throat and groove diameters. So much so he's resorting to a heeled bullet. I checked in here to see if there was something that might help him.

I cast a Accurate 37-285C for my 9.3x62mm Mauser I am quite pleased with the performance of this rifle and this boolit, it is very close to the 9.3-285 NOE that was mentioned earlier
Could you use 7x57R as the parent case for both 9.3x57R and 8x42R? It is a lot of neck stretching to go from 7 mm to 9.3 but the 8mm should be doable.
