Marc 147 Posted August 26, 2012 Report Share Posted August 26, 2012 (edited) 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. edited to make a correction.

going12220 125 Posted August 26, 2012 Report Share Posted August 26, 2012 (edited) 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. http://www.tacticool....com/powder.pdf Edited August 26, 2012 by going12220 Quote Link to post Share on other sites
racenviper 2 Posted August 26, 2012 Report Share Posted August 26, 2012 i would forget the Hornady powder bushings and get this from MidwayUSA 'BPI MEC Powder Bushing Convertor'. With this you can then use the MEC bushing guides for powder. Quote Link to post Share on other sites
