9.3X57 -Brass and loads

[ratherbefishin]

I have most of the components for reloading my ''new'' swede Husqvarna 9.3x57-dies, 8x57 brass,3031 powder and speer 270 gr semi spitzer[never reloaded before]

I would like to duplicate the Norma ''alaska''commercial hunting load for the 9.3x57 ,which I assume would be is pretty good hunting load for moose

Question-on resizing the 8x57-some forums speak of annealing the brass before resizing-is that really neccesary and if so-how do you go about it?

Question-would 45 gr of 3031 be an acceptable powder charge for the 270 speers?

I've never loaded for a 9.3X57 or formed brass for one.

But I do load for a .35 Whelen and all I use is re-sized .30-06 brass. The process is simple. Use lots of lube with a bit inside the neck, then run the .30-06 case into a .35 Whelen FL die that has a tapered expander. A Whelen case emerges from the die.

I don't imagine the process is any different for the 9.3. Just make sure your FL die has a tapered expander. My RCBS Whelen die came with one.

As for annealing, I've never done it.

If you lose a couple of 8mm brass in the process of making 9.3, remember that 8mm brass is easy to get.

would H335, ,3031, and 4895 be similar powders?I see loadings for each.

The 4895 would be the one I would try first, it works great in my 35 Whelen.

I use 48 gr of Win 748 behind the 270 Speer in my 9.3x57 (and in my 9.3x60 as well). I've always formed cases from 30-06 and then shortened them, as I had a surplus of these. - dan

45gr of IMR 3031 MAY be a safe load behind a 270gr bullet in your rifle (or maybe not). I would not use it as a starting load. I have worked up to 45.5gr behind a 250gr TSX in my M98, starting at 40.5 gr. If I was loading for a 270gr bullet, I would have used a lighter starting load. Note standard disclaimer : These loads are safe in my rifle, they may not be in yours. Use at your own risk.

 

[ratherbefishin]

so- how would you find out what Norma loads for their ''Alaska''9.3x57 load?

 

[ratherbefishin]

I would like to understand the connections or similarities between different brands of powder-are there interchangeable groupings?ie-what would be comparable to IMR 3031, 4895,or win 748?

Do you have any problems with thick necks when you use .30-06 cases?

Not sure what you mean by "interchangeable groupings", but I think the connection you are looking for is burn rate. Of the ones you have listed IMR 3031 is the fastest burning, then IMR 4895, H4895, Win 748, with quite a few powders in between. If you have a reloading manual, look in the index, it will list a powder burn rate chart.
