Re: Fast powder vs Slow powder ????

A slow burning powder can cause a secondary pressure spike that is much higher than
the primary. A lab won't even tell you it occured unless you ask them to include it in
the results. The theory is; As the bullet gets a little way into the barrel the powder burn
rate accelerates rapidly due to heat and more case capacity, It catches the bullet as it
slows from the initial burn having not burned all the powder. These spikes have produced
pressures in excess of 150,00 psi and are pretty much ignored (or not talked about) by the shooting industry at large. A faster powder is the way to avoid them. Also your throat
will live longer if more powder is burnt in the case instead of the barrel.
