    Measuring where lands start?

    Thanks for the info guys! 3gun that is what I was thinking. Build my own jig and then at least I will know the exact measurement (coal) for that bullet. I don't plan to play with it too much, but my engineering mind just had to know. It's all part of the puzzle in making that 1km shot! :-)

    Measuring where lands start?

    I have read in a number of reloading forums with regard to bullet seating depth, COAL , and the effects on accuracy, that some loads/bullets do better with a little "jump" before they engage the rifling. I see figures like -0.003 or -0.006 etc. I get exactly what they are saying so my question...
