Thanks John. Sounds like shell technology is part brain science and part rocket surgery. My pea brain says everything is the same except a piece of plastic and the length. Are “magnum” shells more powder, more lead, or both?Yes. Theoretically.
But, changing components and payload weights/etc. may also affect the pressures in a negative manner too. Meaning, you could cause an over-pressure situation. Which as you are sure to understand could end badly.
