I acquired a 1943 Sako M39, in 9,3x53r Finnish a few years ago, and after searching for a year or more was lucky enough to find 4 boxes of Sako 102D factory rounds for it. I have shot one box off, and have 60 rounds left. I considered selling the rifle, but have since decided to keep it and shoot it more.
I have searched high and low for more factory rounds in Canada, but have been unsuccessful. Who knows, maybe I have the only 4 boxes in Canada.
Anyways, today I ordered dies from CH4D so I can reload for this rifle.
Just wondering if anyone out there has load data for this cartridge.
The factory Sako cartridges are 256 gr Bullets and are rated at 685m/sec (2250fps) according to Sako's website.
Something similar to this load would be nice. I would love to have the opportunity to take a deer, or bear with the rifle.
 
9.3 x57 and 9.3x53.3R parent case capacity is 64grs water. (8.x57 and 7.62x54R)

Use the appropriate 9.3x57 load for the same bullet weight.

My 9.3x57 load is 286gr bullet with 44gr Varget and Win LR primers
 
Have a look at that page:

A search for 9.3x57 showed a few articles, the last one which I remembered in Handloader Issue #283 - April/May, 2013:

The 9x57 has a few entries too, but it will be more difficult to find the publications.

Here is a comparison (post 30):

Tried a few loads today.
Loaded up Matrix 250 gr FB Hunting bullets, over Varget powder.
Ran data through Quickload first, went with 48 - 49 - 50 grs of Varget. Quickload shows 50 grs to be very close to 100% capacity, but still stays under the pressure Max by a lot, and should produce approx 2250 FPS which the factory Sako rounds were.
They all shot decent, the 50 gr loads were significantly higher recoil, though only showed the slightest sign of pressure on the primers.
So my next batch will stay under 49.5gr.
