Thread: The perfect Big 7.

The 7mm Blaser magnum case from Norma has a very thick web and base
It handles pressure well
But pressure shows up with sticky extractions if loaded up too hot after a few firings

In reality the following are H2O capacity comparisons to top of case

7mm Blaser Magnum 80.2 grains H2O
7mm Blaser Magnum Improved 83.5 grains
7mm Remington Magnum 85.0 grains

The 7mm Blaser magnum is still a great case that fits in a Tikka magazine nicely but a 7mm Remington Magnum is simpler and cheaper to run
