There's SG16 and a short SG16s. I don't use the "short".
Filling the hull is all about density of powder once you have a wad with the tallest cushion section.
SG-16 has the tallest crush section - and the powder cup is filled with little bumps that take up more space.
For example - 24 grains of SR4756, SG-16, and 1 ounce #8 shot is a perfect fit in Cheddite hulls.
