I developed a load for a 300wsm with hornady brass. I was given a bunch of once fired nosler brass. I weighed them both the hornady was 237gr and the nosler 245gr. I have never really looked into this. I understand the nosler will have a smaller capacity because it weighs more, but how much if I want the same bullet to shoot with same powder how much will I need to reduce the load? Is 9 grains even enough to make a difference?
