I do....

I use equal amounts of shot and powder. Powder charge is Pyrodex RS.

I also use a plastic shot cup to help keep my pattern tight.

What you need to do is get out there and try different charges (powder amount vs shot amount) and find what patterns good for you.

I use 100 grains of powder and use #4 copper plated lead shot.

The gun is a Pedroselli - 10 ga. side by side.
