TG is a very dense powder. I have been using it for 1 oz 12-gauge loads. Wad selection is very important. Because of stack height issues (dishing) I don't use the CB1100 wad for 1 ounce loads. I find the gray 7/8ths wad works better with 1-ounce loads in Remington hulls. My best load is a Remington GC hull, 17.8 grains TG, CB 0178-12 wad, Win 209 and 1 ounce of shot.
