Whatdoes dram equivalent mean is shotgun loads? Thanks for the information guys.

It goes back to the days of blackpowder. Today's shotshells are loaded with smokeless powder. The dram equivilent is nothing more than a number expressed in drams, which is a blackpowder weight. The shells are loaded to the same speed. An example would be a 12ga load....1 1/8oz-#7 1/2 shot -2 3/4 Dram Eq.This would mean that the load would roughly have the same velocity as the old black powder load appx 1145fps
