@Caprivi:

I think that Norma is producing target cartridges in 9,3x57 with a FMJ bullet of approx. 230grs weight. These are sold in boxes with 50pcs. at areasonable price.
For hunting Norma offers the 286grs Alaska SP and maybe (still) the 232grs PPC Vulcan.

I had very good results with the 270grs Speer SPRN for target shooting.

best regards
Rolf
