help with quickload barrel time

[Dwh7271]

RR,
Don't rule out the 140s until you run some over the chrono. Remember you probably have 2% to mess with around the node.
Not beating up on it at all but the QuickLoad burn rates are frequently off, sometimes a bunch. Load some up with a powder that may be close then adjust for capacity, weighting and burn. You may be surprised.
If you ever need to guess it, nodes are frequently about 3% apart. Not exact but close.
Or run a barrel time run.
Easiest way I know to do it is choose a powder, look in the barrel time box on the bottom right box, adjust grains until it hits the barrel time you want (pressure doesn't matter for this cheat as you're not going to load it anyhow :grin: ). Then up on the toolbar where you hit the box/button to calculate a powder run; hit the RIGHT button(normally gives the all powders run), when the pop up box comes up check the barrel time based on existing load (or something like that, it's the only one that says barrel time) and view the output.
Sounds harder than it really is.
That may help you out.

Thanks DWH. I've already done all this, including chronograph I ng some 140s. I was reading another forum where one fellow says there is reason to believe that barrel time is more closely tied to peak pressure than muzzle velocity. I found that interesting but haven't really digested the rationale for such a theory.

I'll be taking a much closer look at all this, that's for sure!
