Powder\Velocity\Accuracy

Powder\\Velocity\\Accuracy

Why can two powders, pushing the same bullet at the same velocity have such varying levels of accuracy? I don't question that it's true, but why? /ubbthreads/images/graemlins/confused.gif

Burn rates maybe ???

Differing peak pressures, bullet acceleration and barrel harmonics.

That's my uneducated guess. /ubbthreads/images/graemlins/smile.gif

Re: Powder\\Velocity\\Accuracy

I would stress barrel harmonics. Different Rifles of the same make, and same cartridge will shoot the same bullets differently. That is my uneducated guess!
