Powder Bar Chart

[dd in MA]

I have six 00 powder bars with measurements on them of:

.272; .291; .302; .315; .320; and .328

Does anyone have a conversion chart for these?

I have a CPM 00 charge bar with interchangeable bushings and some of the bushings are close to the sizes you list. They are:

No. 8 (about .275) Bullseye=4.4? Unique=4.5? 231=5.3? 2400=NR? 4227=NR
No.11(about .302)? ? ?"? ? ? ? 5.2? ? ? "? ? ? ?5.4? ?"? ? ?6.4? ? ?"? ? ?NR? ? ?"? ? ?7.5
No.12(about .214)? ? ?"? ? ? ? NR? ? ? ?"? ? ? ?5.8? ?"? ? ?6.7? ? ?"? ? ?7.9? ? "? ? ?8.0
No.13(about .327)? ? ?"? ? ? ? NR? ? ? ?"? ? ? ?6.5? ?"? ? ?7.6? ? ?"? ? ?8.7? ? "? ? ?8.8

This may give you some idea of what your bars will throw. There used to be a CPM chart on this site with the photos and I'm sure it will be there as soon as the photos are up and running again. The chart is a little incomplete as they don't list Bullseye charges any higher than the 5.2 grain charge for the no. 11 bushing and thats about my starting load for the 45acp with many bullets!!


UPDATE

Oops! I told you wrong. This is for a 00 measure with a .1875 riser. The total thickness of the bushing is .500 inch. You would have to multiply these charges by .625 to get close to a 00 bar. This is assuming your bars are .3125 thick.

The following data comes from a spreadsheet that I created from measurements from some of the powder slides that I have.? Measurements are in inches, but the final volume is in cubic centimeters.? I found that most of the Star powder slides have a tapered hole, so to get an accurate volume, you have to measure the top and bottem diameters, then take an average.? ?Lee includes a very useful chart with their autodisk powder measures that has volume in CCs across the top, and the equivalent powder weight for most popular powders.? I use that chart along with this data to choose the best powder slide for the powder charge I want.? I find for example that the current Bullseye powder always results in heavier charges than you would expect from the markings on the powder slides, but if you use the volumes below, to find the charge weight on the Lee chart its pretty much right on.
