Appreciate the input. The brass is nickel-plated, so I don't know how that affects things, but trimming is needed after each shot. It is Roy Weatherby's oldest caliber (.300) so you know the pressures are significant. I'm at 5 reloads now so....I guess I'm done. I kills me to fork over the $$$$ when the brass looks so good (& it's hard to find the nickel-plated stuff too). The primer pockets are still good and it cleans up beautiful...oh well.
