This is a revision of the chart I put on Captain
Baylor's Ranger Camp in 2005. Then I used an adjustable |
|
|
|
|
measure to measure 100 gr. FFg by weight then use
that measure to produce the same volume of Black Powder Substitutes. |
|
|
This time I started with a 4.0 cc. Lyman dipper and
weighed 5 samples of each powder, then averaged. |
|
|
|
|
Black Powder Loads are normally measured in volume.
15 gr. vol. is 1.0 cc. |
|
|
|
|
|
|
1.0 cc. weighs approximately 15 gr. This chart
converts to weights of equivalent volumes. |
|
|
|
|
|
Weights were rounded to the nearest .1 gr.
Duplicating results closer than the nearest grain using BP and subs is
difficult and unnecessary. |
|
The old chart is still on the site at : |
