Powder throw cross refrence?

[bdotson]

I once had a chart it was in a excell spread sheet that gave a cross refrence for most powders to clicks useing a harrells powder throw. I cant seem to find it and I cant remember where I got it. Does any one know where I can fiind one? I was very simple just had clicks to grains for several powders. Thanks Buddy

There are measure to measure variations, even within the same brand and model, that make converting weight to clicks as if they were a standard unit of measurement a bad idea. Additionally, anyone who has spent much time with a measure and scale, has learned that the amount of powder thrown at any give setting is technique sensitive, and there is no way to really know exactly how someone else throws powder. I would suggest that while clicks are convenient to work with when throwing charges at the range, that you take the time to weigh a representative charge or two, and record that, along with your other data for a particular load.

As far as noting different powder densities goes, I throw ten charges, using the same technique that I always use, at a setting that is below the lowest charge that I would probably use with that bullet, in that caliber, and weigh them all at once, and then divide by ten to get the average charge weight. I then do the same thing slightly above the maximum that I think will probably be used, and then subtract to get the difference. Dividing the difference of the two averages by the number of detents between the settings gives me the value of one detent, and multiplying that by the number divisions between each number, also referred to as clicks, gives me weight per click. My measure has six units from one number to the next, so my settings between 52 and 53 clicks are 52, 52 1/6, 52 2/6, 52 3/6, 52 4/6, 52 5/6, and 53. In the range that I use 133 in my 6ppc, 133 comes in the least dense of all the powders that I have tried at something like .089 ( I forget the exact number; my record book is in my range kit.) grain per sixth of a click.

bdotson, I have one of Homer's charts here and I'd be glad to FAX it to you or, just photocopy and mail.
