Thank you for the comments. I did a new series of loads and decided to use new brass. I don't think there should be any excessive pressure issue if the load is below maximum and the case has some room (whether brass is new or fired/resized before). I just want my load to have sufficient velocity and best accuracy for hunting.

Here are the load data (yet to be fired and tested):

7mm Remington Magnum: 60 - 62 grain Norma MRP, Lapua Naturalis 155 grain bullet

300 Winchster Magnum: 72 -76 grain Norma MRP, Lapua Naturalis 170 grain bullet

300 Weatherby Magnum: 82-86 grain Norma MRP, Lapua Naturalis 170 grain bullet


And here are some pictures:
