How many 1 1/8 oz. shells can you get out of 25# of shot?

If you load 25 pounds of 7 1/2 shot and then load 25 pounds of 9 shot with the same bushing that you used for the 7 1/2 shot, you will not have the same number of shells from each batch. Because the 9 shot will more completely fill the air space within the shot bushing you will hence have more weight as compared to the same bushing filled with 7 1/2 shot. You will get less shells from the 25 pounds of 9 shot. Ken

All loaders load by volume. This is true for both powder and shot. The loader has no way of loading by weight. Therefore you alter the volume by changing bushings in order to reach the weight your are seeking.

You guys are saying the same thing different ways, Revbook uses a custom bushing for each size of shot that drops exactly 1 1/8 oz. Montanaken is saying if you do not have a custom bushing the shot weight will be different because the volume of 9's vs. 7.5's in the same bushing will be different.....

There are no reloading machines that weigh the shot drop. Just like there are none that weigh the powder.

Therefore you must alter the bushing/bar or use an adjustable bar to get the same weight from different sizes of shot.

What is gained isn't worth the effort.

Some get it, some don't. The simple fact is that every loader I have ever seen or used, accomplishes both shot and powder drops by volume. There is no weighing going on of every shot and powder drop unless the operator is weighing "AFTER" the machine has made its drop by volume. That said, every shot/powder drop fills the bushings by "VOLUME" every single time. Some understand this basic principle and some don't.

revbook, you only served to prove my point in your example above. The volume changed because the shot size changed. You do understand that when the volume changes, so will the weight?

As the size shot decreases so does the weight of each pellet. I doubt there is much variance in the final weight of the shot dropped. If there were big differences, charge bars would be made & marked "1 1/8- 7 1/2 shot", "1 1/8- 8 shot", etc.

Well maybe its a little of both. Hornady makes 1 and 1/8 bushings for 7.5, 8, 8.5 and 9 shot, and each one varies slightly in inside diameter with the 9 shot bushing being the smallest diameter and the 7.5 being the largest. So is that for volume or weight. I'm leaning toward weight, since you can fit a more dense amount of shot in a cylinder with smaller shot. I am thinking a cup full of ag lime would weigh more than the same cup full of 53s. But I have never tried that.
