[QUOTE="nodakhunter, post: 1747765, member: 111782"] The whole idea of a ladder test is to try to find a velocity node for your particular barrel/bullet combination. In my experience, if a load shows roughly the same velocity for 3 or 4 different powder charges, that is a good indication of a node. From your data, the charge weights from 57.6-58.2 gr all showed about the same velocity. A good place to start might be to load 12-15 rounds in the middle of that node (57.9 gr) and test them out. If you're happy with the velocity and accuracy, then boom, you've just found a good load without a ton of effort. As for your second question, I've noticed that same exact thing when testing loads out of a .338 Lapua over a Magnetospeed, and I have no idea why it happens either. P.S. H4831SC is an awesome powder - works great no matter the temperature. [/QUOTE]
