I've been loading 8x57 longer then any cartridge. I still try new loads all the time. 1st off. What is the rifle? What is fine for one can be an issue for another model.
Edit: always start w/ low load data, even w/ a new lot of the powder you have been using.
Freedom is not free. The best of us always leave too soon.
