[QUOTE="4ked Horn, post: 100797, member: 11"] Green thank you. [ QUOTE ] I would think that a dissenting point of view such as mine would be helpful when trying to gather all of the facts. [/ QUOTE ] This last reply was a dissenting point of view. Still a bit of a hijack of the question but I'm not the hijack police and I know I do it all the time. None the less, it is at least something that can be discussed. [ QUOTE ] If we could factor the wind out of the equation as much as possible--by shooting at 100 yards [/ QUOTE ] Or by graphing the relative vertical impact height of the ladder sequence perhaps? It has been my experience in learning to read ladder tests posted by others and now my own that plotting the shots on a graph has shown definate grouping patterns similar to the high and low groups shown on your bbl vibration diagram. The same goes for plotting velocities. There seem to be certain patterns that at the very least reveal a glitch in the increasing velocity string and often show and corespond to the impact patterns. [ QUOTE ] Too, chronographs sometimes get it wrong. A little bit of unburned powder follows the bullet through the sky screens and a read error occurs. [/ QUOTE ] They more often get it right within a certian tolerance. And I'm going to have to say the powder thing is a bit of a stretch. Infact I know that the chrono I have been using has a delay in it so this dosen't happen. You can override this delay if you want to measure the cyclic rate of full auto fire but is an override on the auditory sensor and not the skyscreen start and stop sensors. [ QUOTE ] But for those lurkers out there that are still wondering about the OCW method, and whether or not it offers the distinct advantages over the ladder method which I claim that it does--I hope I have made some sense here. [/ QUOTE ] And for those who, like me, are trying the ladder test for the first few times and are not getting the feedback as plainly as we might have expected and are doubting that you will be able to find the same benefits from this test that hundreds of benchrest competitors claim it offers-- I hope I have also made some sence and given you the encouragement to stick with your plan until you have the experience to know that you want to find another way (or not). (Green, I hope you are still having fun. It is mostly about having fun.) [/QUOTE]
