Thread: Case capacity effects on velocity

Hehe Dave, no TV, so lots of time to read and think about these types of things.

The physics of it fascinates me... Would you get higher or lower pressure (and resultant velocity) for a given power weight and projectile weight if the combustion chamber is larger or smaller ?

Higher pressure is supposed to happen in military cases as the walls are thicker so you have to back off the load.

Wait til you get hooked on the tribology....a great sleeping aid.
