ken, glad to hear you are up and about. now lets get down to the brass tack here. The answer to the question is which weighs more a pound of lead or a pound of feathers. I usually lean towards the lead [img]images/icons/wink.gif" border="0[/img] Yeah I know they weigh the same, it's that darn liberal arts education poking it's nasty head up again. But the volume of the two is considerably different. Take fire wood for example there are many species of trees some not at all dence such as cotton wood and others so dence they will not float on water such as ebony. The potential available energy in each type of wood is proportinate to it's density as woods are are similar. However gun powder is a different fish alltogether. Being a man made the stored energy is dependant on it's make up. Take 4227 it comes in 1/2 pounds while most others come in pound cans. Staying with IMR family you will find the that velocities generated from equal cartridges are not divided in half if the same weight of powder is used. Black powder is measured by volume rather than by weight because it's composistion is such as it is not a precise explosive. Alittle more or a little less makes little difference in power developed. Don't try that with Bulls Eye. What it comes down to is that we are playing with fire here and it is best to follow instructions.<P>Bullwnkl.
