I have a Husqvarna 1640, chambered in 8x57JS. I shoot practically exclusively 196/200 grain bullets.
Loads that have given the best accuracy and velocity are built with Vihtavuori N150/N550 or Hybrid
100V. These are all in the 4350 burn rate area. I am getting 2500/2550 fps without pushing the
envelope in the longer barrel.
Your rifle is fairly light, so recoil will be noticeable if you load to it's potential. Good luck! Dave.
