[QUOTE="Lou270, post: 2831467, member: 5352"] That is getting a bit nebulous and fudge-factory and well beyond the accuracy of the tool. In any case, pick a bullet in GRT which probably has a start pressure around 3k and run your load. Record the velocity and pressure. Now change the start pressure to 1000 or 0 or whatever and get your velocity and pressure. It will be lower. Now increase the charge back up until pressure equal and see velocity. I would bet few 10s of ft-second which is in the noise of velocity variation. Some folks are showing several hundred ft/s difference and showing higher velocity with same powder charge. That is not representative of lower pressures given the relatively small knob dealing with Lou [/QUOTE]
