Here's what I got....my friend started out with some VV N550, didn't get great accuracy and found it to be temperature sensitive. He has had some better results with Varget, starting with 66 grains and ending with a MAX load of 68 or 68.5 grains. Bullet used for these loads was the 225gr Accubond. I'm sure I don't need to say it but....use caution!
