I think what the spank meant was dram equivalent. In the old days, way before you were a Canuck. black powder loads were measured in drams of black powder. To be honest, I do not know which method you mention that they used to measure. When ammo started to be loaded with smokless powder some still wanted to know how powerfull the load was. That is when ammo manufacturers started to use Dram equivalent. At certain amount of black powder was used to propel a certain amount of shot and a certain velocity was expected. eg 3 drams of BP pushed 1 1/8 oz shot to 1200 fps and 2 3/4 drams pushed the same amount of shot at 1145 fps. Today any amount of smokless powder that can push 1 1/8 oz 1200 fps is refered to as 3 dram eq. load and a 2 3/4 dram eq load one can expect 1145 fps. Salter I know you probably know this. My post was just to clarify for the younger pups out there. It seems to be very confusing unless you have been brought up with dram equivalent. I think all one needs to know is amount of shot and velocity and some ammo manufacturers are doing just that.
Yes, I did know that, just trying to make the point of being clear about terminology. For interests sake, the measurement system used to measure drams for ammo was the Avoirdupois so this would have worked out to about 82 grains of black powder. Chances are this wasn't weighed anyway, so there were likely small scoops, medium scoops and large scoops.
While the bottle is not labelled in drams, my shooting friends and I do enjoy a wee dram of single malt now and then. While the more correct definition of a liquid dram is equal to about 3/4 of a modern teaspoon, we like to use the informal measurement of a dram which is about 1.3 ounces (UK). I suppose more correctly, we enjoy several drams of single malt as one dram just wouldn't be worthwhile.
