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.

Greetings,
My experience with the Accubonds is the same. A paired load test with the 6.5mm 129 grain Hornady Interlock and the 129 grain Nosler Long Range Accubond delivered 100 fps more velocity for the Accubond with everything else the same. This equates to a lot more pressure as well. Nosler publishes just one set of data for each weight of projectile so I assume that this is for the harder ones.
