Is there "something" pushing velocities...?
This is a question i have wondered....
In all our reloading manuals.....there is published velocities....with a given type and amount of powder and bullet....,,..... lets say powder A vs powder B.....
Powder A has a published velocity of 3000 fps....
Powder B has a published velocity of 3100 fps...
So, on the face of it...powder B will deliver more velocity and more "punch"....... but my question is this in the above example......
Is there characteristics of a powder that deliver more "punch",,, than what the numbers indicate... ie, are there inherent characteristics in some powders that do not show across a chronograph...???
thanks for responses....
