They are Cheddite hulls so you can use any recipe calling for that hull. Ballistic Products has a number of recipes in their reloading manual but they are pretty much specific for their lines of components which aren't usually cheap. Hodgdon had specialty loads in their shotshell manual utilizing common components if you can find a copy. Otherwise, Double Gun Journal and their website should be able to point you in a general direction. Failing that, any Federal recipe would work too if dealing with 2 3/4" hulls. You might have to adjust the crimp settings slightly depending on your components.
