I was curious to know what the difference is between a 7/8 ounce load and a 24 gram load. Tonight, I decided to do the math.

Code:
7/8  Ounces = 0.875    Ounces
  24  Grams = 0.846575 Ounces

Or vice-versa
Code:
0.875 Ounces = 24.805832734375002 Grams

O.K., so the difference in weight between 7/8 ounce and 24 grams is (.875 ounces - 0.846575 ounces) = .028425 ounces.

I reload a lot of #8 shot. According to the chart there are 409 pellets in 1 ounce of #8 shot. Therefore a single pellet weighs (1 ounce/409 pellets) = 0.0024449877750611246943765281173594

Now how many pellets are in 7/8 of an ounce? (409 pellets/ounce * 0.875 ounce) = 357.875 #8 pellets in 7/8 oz.

And how many pellets are in 24 grams? (409 pellets/ounce * 0.846575 ounce) = 346.249175 #8 pellets in 24 g.

The difference in pellets is (357.875 - 346.249175) = 11.625825 - less than 12 pellets!

And the weight difference is (11.625825 pellets * 0.0024449877750611246943765281173594 ounces/pellet) = 0.028425 ounces

----------------------------------------------------------------------------------------------------------------------

Changing to #7.5 shot, the numbers look like this:

According to the chart there are 345 pellets in 1 ounce of #7.5 shot. Therefore a single pellet weighs (1 ounce/345 pellets) = 0.0028985507246376811594202898550725

Now how many pellets are in 7/8 of an ounce? (345 pellets/ounce * 0.875 ounce) = 301.875 #7.5 pellets in 7/8 oz.

And how many pellets are in 24 grams? (345 pellets/ounce * 0.846575 ounce) = 292.068375 #7.5 pellets in 24 g.

The difference in pellets is (301.875 - 292.068375 ) = 9.806625 - less than 10 pellets!

And the weight difference is (9.806625 pellets * 0.0028985507246376811594202898550725 ounces/pellet) = 0.028425 ounces (the weight difference is the same - only the number of pellets will change)

Uh....Yes,,,,it pretty much doesn't matter unless you're shooting Olympics/International comps----or Olympic qualifiers. A judge will take two shells from each shooter to weigh the shot charge----before each round. And these have to be new shells but it doesn't matter if they are new, if they're overweight----you're outa here.

So manufacturers try to drop 6 pellets less than 24 grams, just to make sure those using their bullets don't get disqualified.

It still happens though, rare as it is. :roll:

I thought that a Chinese shooter got a DQ for too much shot in a recent olympics.
