Optimizing Quickload Data with Burn Rate and Bullet Weight Changes

Here is a great link for those who are using Quickload and trying to get their Quickload data to more closely match their chrono velocities .

    I've been hoarding all of the good info for a while. I figure it's time to share. LOL
    Let me know how it works out.
    I've been able to tweak the values very close.

    Just purchased QuickLoad!

    I'm a little curious as to how much you guys are having to fudge the burn rate factor and bullet weight, to get Quickload to match your emperical data.

    Using all the cartridge dimensions, I'm able to get everything to match up by adjusting the burn rate factor, but the velocity will be off quite a bit when I reduce the charge wt. I've tried decreasing and increasing the bullet wt. a few grains to see if it would help, but I just can't seem to get the velocity to match up for two different charge wts.

    Also, what initiation pressure are you using, and for what situation (bullet seated .010" into lands, right at, or sitting out some distance).

    I've never had a problem getting pretty darn close (within 1-2%) with just adjusting the overall length and the water capacity of the brass.

    What Chrono are you using?
