Thread: Old Data and Load Variations. Traps for New Handloaders

I know bullet jacket shape and thickness impact pressure,
ie ELD-X vs ELD-M. the X needs less powder as its thicker jacket creates more pressure as it enters the rifling.
another trap
Sierra 225gr Gameking vs Nosler Accubond 200 gr. The Accubond needs less powder to hit pressure, It is longer impacing case volume and the thicker tougher jacket is harder to start into the rifling. Based on GRT reloading model and my experiance.
