I just got 3kg of N 568 and would like to try them in my 7 Rem Mag and 257 Wby. I have looked on line and there is nothing. I figured if any body would have info it would be here. Iwant to use the 115 VLD in the 257 Wby and 160 to 168s in the 7.
 
So judging erom what I found on the Vihta Vouri web site. A Wise person would use the data for N570. Start at the the starting load and work up from there. They have no data on either or the cartridges I was looking for containing both powders.In fact they don't include the 257 Wby in there data. I hope theis helps some others.
 
I used the Berger 115 and n568. I am away for my notebook at the moment. I was able to start low enough and work up to 3350 with good case fill. I just got mine rebarreled to a 1-7 twist, going to use n568 with the 133 Berger and 134 eldm.
