    To help sort out the various kinds of ammo, I made the following chart that compares the weight and number of balls per pound of different kinds of ammo. It shows for example that for .40 cal lead, the closest steel ball is 7/16", and the closest clay ball is 18mm (depending on the density of clay, which varies widely).

    The numbers for hex nuts (and probably most of these kinds of ammo) are approximate - I'm not sure how standardized they are across all manufacturers. Densities are mostly taken from this source:

    Edit: @Clever Moniker kindly gave me permission to copy the companion ammo energy chart here, for ease of reference.

      I actually think this is worthy of a sticky.

      If anyone would like to see some other sizes, just let me know, and I'll add them to the chart.

      Would it be possible to add a common range of hex nuts (if possible) ted? :)

      @Clever Moniker, I can look into it, but I'm not too familiar with the common sizes to include in the chart. Can you suggest a range?

      there is also the issue of imperial and metric sizes @Clever Moniker? M8 weigh in at 4.5 grams. M10 at 10.5 grams and M12 at 15.3 grams.

      Yes, obviously there will need to be imperial and metric sizes.


      I think Toddy has the right idea here with:
      m8, m10, m12

      For imperial, maybe:
      5/16, 3/8, 7/16

      I added a few hex nuts to the chart. Thanks @Toddy for the weights on the M8, M10 and M12. I have a feeling though that the exact weights vary across manufacturer. Also, there is apparently something called "heavy hex nuts" which are a little less than double the weight of "standard" hex nuts; the chart shows "standard".

      Funny. My two favorites are a step apart. 5/8 marbles and 7/16. I knew I saw some regularity in their performance.

      Sure, I can provide it as a PDF for the Montie Gear website. No need to credit me personally, but maybe you could provide a link on your site to the appropriate thread on SlingshotCommunity.com, so people could see the discussion and join the forum if they haven't already.
