    What measure do people use to determine the number of empty hulls they have by weight? I have a couple of 90 gal containers that I keep my STS and Nitro hulls in. There are a lot of them there and my kids asked me how many I have? Well I don't really know, but we can certainly find out.

    If you have a good measure of the number of hulls by weight, say for Nitro/STS and Federal Papers, I would very much appreciate that info. Thanks in advance.

    You will need to know the weight of the containers when empty and when full. Then weigh a single hull and then divide the difference between full/empty container weights by the weight of a single hull. Sort of like this: (full - empty)/single hull weight = number of hulls in container.

    Put an empty hull on your powder scale. You will have the weight in grains. Divide 7000 by that number and you will have how many hulls per pound. Now multiply the weight of the hulls in the container by that number and you will know how many hulls you have. HMB

    Sorta like that, but I'd weigh 10 or even 100 so you get a good average. And, as said, you need to know the weight of the empty container.

    I occasionally sell hulls and I'm not about to count out 500 hulls. So I measure them by the hundred-weight then throw in a couple extra hands full.

    Thanks guys,

    I can do the math part, I was just curious to see if anyone had emperically found good values that correlated well. If not then it is off to weigh hulls. Thanks again!

    Looks like about 56 hulls per pound. For STS.

    Thanks Nebs. That is exactly what I was looking for.

    Gallon ZipLock freezer bags hold about 100 hulls. Bob

    You will have something like 8100 hulls in a full 90 gallon container.

    Take 50 or 100 hulls in a plastic freezer bag to the market. Go to the fruit section and weigh them. Very Easy

    When my grandkids wanted to know how many hulls I had, I gave them a counting job... after counting multiple thousands of Premiers as well as STS and Nitros, they know what a once-fired hull looks like and what hulls Grandpa likes to harvest...

    Make it a learning experience...

    I am making it a math learing experience. I am an engineer and this is the kind of problem one might solve if they are interested in the field.

    So we will make some predictions based in the data provided here and then make some measurements and see how close the predictions are to actual results. :)

    It is a bit much for 5 year olds to understand, but that's ok.

    I guess 150 pounds for a 90 gallon container full. 8100 hulls reloaded 6 times each would make about 200 flats. Shooting a flat a week, almost a 4 year supply. Depending on how old you are, you better keep hoarding. Mark

    I just did mine and glad I did, because I need more hulls!!! AA's measured out to about 54.71 per pound. I averaged ten hulls and they came to about 127.91 grains per hull. I ended up about 5200 once fired, and 1,500 loads which will get one more load, and then see the garbage. I would like to be at about 10,000 once fired.

    Any idea of the interior dimensions of the containers ?

    Sounds like AAs may be a tad heavier than STS. When I prognosticated 56/lb for STS, I used 125 gr. per, which was rounded up from 124.5 gr. for the one I weighed.
