How many grains of smokeless gun powder are in 2.5 cc's?

Answer 1

What we are trying to do is find the volume of one grain an convert that to CC's.

This called Volume Measured Density (VMD). 1 VMD = cc

Lee Precision has a list at:

http:/www.leeprecision.com/cgi-data/instruct/VMD List.pdf

Alliant Red Dot Smokeless powder has a VMD = .14130

So to find out how many grains the formula would be:

2.5 cc divided by .14130 VMD = 17.693 grains

If your load called for 9 grains of Alliant Red Dot Smokeless powder.

The formula would be:

9 grains times .14130 VMD = 1.2717 cc

Be aware that powder companies have a plus or minus tolerance of 10% to 15%.

Hope this helps.
