I just got 100 Norma 300 WSM brass cases. I weighed each one and 65 of them were within 1.5 gr of each other (+ or - .75), 31 were about 1 - 2 gr heavier than the majority bunch and 4 were about 1 - 1.5 lighter. Anyone think these differences will affect shooting results? Should I separate them or throw them all in together?
Next, they will at least need neck sizing, should I just neck size or full length?
Last, I plan to just neck size the reloads after their first firing, will the diff in case dimenssion from virgin brass to fired brass affect pressure, velocity, accuracy etc?
My previous experience with reloading has been with fired factory ammo brass, Have never loaded virging brass.
Would appreciate your insights on these questions and any other insights on this topic.
