How to choose the TSS size ?

Each chart corresponds to a game. The distances are in column and the size of TSS in raw.

In each cell, there is the load necessary to respect the pattern density of pellets necessary to reach the game with the appropriate number of balls (generally 4,2 on average and 8 in the center).

For a wingeon, for exemple, this minimum pattern density is 180 balls in a circle 30" in diameter. You can also find in column the number of balls for 10 g of shot.

When the cell is in white, it is because the penetration is not sufficient for the game considered. When it is in blue, it is that it is the optimal charge in simple shot. In green, it works too but it is not optimal.

In fact, using the chart, you can know what you should shoot if you know the distance and type of game. For example, a vingeon duck at 60 m will be killed with a 29 gr of 9 1/2 but it is relatively border line for the penetration level. With 9, it will increase to 34 grams to ensure the pattern density of 180 balls.

If the explanations are not clear enough, you can leave a comment (registration required) and I will answer quickly.

    I have been learning to load TSS loads for a little over a year now, and love studying new duplex combinations.

    I’m interested in making one that can be dual purpose for mallards &geese.

    Have you ever made a blend of 9-1/2 tss @ 7 tss?

    Do you have a number that I could call you on to discuss? Im looking for an ammo reloading friend & supplier?

    Do you have any load data for 3” 410 using the spherotungsten 18g #9s for ducks? I’m just getting started with loading the tungsten and would prefer not to over pressurize it and lose my face LOL. I’m using H110 for my regular field loads and would like to use it for these loads as well since I already have it; just need to know what grains to start working with.
