[QUOTE="J E Custom, post: 465443, member: 2736"] There are several things that you have to buy to do volume testing properly. First you need a laboratory Buret (A Glass measuring device). Then you have to have a source for demineralized water. Also you have to add a wetting agent to eliminate the surface tension. (To get an accurate measurement). The cases must be clean and free of any dust or oil before you start the volume testing. Now you are ready to start; Fill the Buret up with the treated water to a Zero mark and using the petcock fill the test case. (Case must have a spent primer installed upside down). When the case is level full stop filling and wright down the volume of that case on the case it's self for later sorting. If you mess up filling a case you must dump it out and set it aside for drying and testing later because there will still be some test media in the case and render a false reading. I have tried using a granular media (Like powder and found it inaccurate) because it is granular and packs differently each time you place it in the case. (Sorry Dave). Ball powder was the best, but it was still not precise enough due to the voids between each grain.I used the same powder charge and dumped it from different heights and at different pour speeds and got varying results. (It was not precise enough). If you want to do a precise volume test the liquid method is the best way. I am sure some will disagree with this process and I'm not trying to start another heated debate because this thread has wandered off in a different direction that the original poster probably wanted. But this is the proper way to test for volume and is used in laboratories. I have all the nessary equipment and skills to do volume testing and have done so and it is a painstaking and time consuming process and is the most precise of all methods. you will have to decide if it is better or worth the effort. I hope this helps. J E CUSTOM [/QUOTE]
