[QUOTE="HaroldNRAEndowment, post: 1940726, member: 111610"] First I will apologize up front for I am in a hurry this morning and do not have time to absorb all the details. That being said, all firearm users should be aware of the following. When one looks on the specifications of powder, you may find a minimum and maximum temperature the powder should be stored. Think about a person that stores the ammunition in a vehicle. Inside vehicles can go up to 160/180 degrees under certain conditions and then there is Winter conditions. Also what enhances the breakdown is a continuing Heat/Cold cycles. Then there is one more part of the equation. Everyone knows what a vibratory cleaner is. Most powders are generally made of the same chemical until one gets into the latest powders that have two basic chemicals. So the next statement is there are hundreds of powders that burn at the varying rates using the exact same chemical. There are 2 basic ways the burn rate is changed. Shape of the granule that changes the surface area that will react with the Hot Gasses from the Cap(an explosive) and then there are Micro-Coatings that ****** the rate of burn. Regressing a little, I have driven on hard dirt roads, what is known as a wash board roa), that have ripples in it. One time I was driving down one of these for the first time, and without exaggeration, the vibration was so bad I was wondering it if was tearing up the vehicle, electronics etc. and that was in an interim about 15 minutes. If a person lived in the country on unpaved roads, or hunted regularly under these conditions, The vibration is no different than a vibratory cleaner.
