    I've had to buy some nosler brass instead of my usual remington brass for my 300rum, is this going to upset my loads and fps ?

    You won't know until you tried loads with both. Sometimes a brass change makes no difference.

    Better back off the charge and work back up. If the brass is stiffer and has a smaller case volume pressure could go up. I seen a proven load that was plenty safe go to leaking primers with a brass change. Took 3 grains less to get it back down to where it was before and to the same velocity.
