[QUOTE="johnnyk, post: 1020174, member: 307"] I think the capacities variance of the different brass changes the pressures of the given load, which affects your barrel harmonics, velocity and POI. This, at long range is a deal breaker. Last weekend I was working up a load for a friends Remington .223 heavy barrel. I was using the same bullets (52gn SMK), primers and powder, but Hornady and Remington brass. Using the same point of aim, the Remington loads printed 1/2 an inch higher than the Hornady's. This was a mild load (23.0gn of Viht N133), imagine what a hot rod magnum load, near max pressure, would do. I think this is where the recommendations to sort your brass, in headstamp and weight, comes from. Just my $ .02 worth. JohnnyK. [/QUOTE]
