[QUOTE="IAHNTR, post: 1209889, member: 76649"] All I've read (a lot) says the magneto changes POI, but group size is the same. At 500 it changed POI ~3.25 moa high. We were also following a testing procedure that was highlighted by 6.5 guys and is done on the premise that you use the speeds rather than where the bullets print on paper. It's done this way to completely eliminate shooter error. You could essentially shoot them into a pile of dirt and get the same info. And, since my brother doesn't shoot a whole lot, we thought this would help eliminate his discrepancies. Where the flatter spots on the velocity graph show up are where the "nodes" would be if doing a regular ladder. We shot 3 at each charge weight to get a good velocity average, see the ES on those charge weights and be able to average the 3 (instead of 1) for the basic ladder. We just combined 2 different load development methods together. Thanks for the input. [/QUOTE]
