need help with pacific 366 powder bushings


Recommended Posts

bushings give you a volumetric measurement of your chosen powder. The weight (in grains) of a powder charge dropped from a bushing is effected by powder type, granule size, density and environmental factors like ambient temperature and relative humidity...basically, to many variables to be able to list charge weights per bushing per powder only to have it all change when a new batch of the same powder hits the market.

 

Your best bet is it to drop several charges from each bushing, weighing each charge and then calculate the average for each bushing with your powder...then make your own chart so you always have the info handy.

well if all else fails there is a mathematical way:

Clays has a VMD of .1462

measure the bushings

use the IDs radius squared, times pi, times the height to get the volume of the bushing

convert this to CCs

and divide by the Clays .1462 value and that will give you a good estimate of how many grains each bushing throws.
