[QUOTE="BrentM, post: 2190451, member: 61747"] So you have 5 fps es over a .8 ladder. That's weird and makes me wonder about your chrono. In this case, I'd reshoot the ladder with 2-3 rounds, probably 3, in .2 grains and see if things line up. Clearly, based on first test being accurate, you are in a wide velocity node. There are lots of ways to get the end result a person wants but velocity ladders are absolutely one of the best ways to develop loads and exactly how I do it. Ladder with labradar or magneto, and find the upper node. Hone in on the middle are of the upper node looking for low SD and accuracy. Usually in the node, you will find a .2-.3 variance yields similar results of low sd and acceptable accuracy. [/QUOTE]
