This has probably been covered, multiple times,, but I think it's good to bring even formerly discussed ideas to the forefront for newbies like me.
I just got off the phone with Reloading Specialties. I had called about their Heavyweight 13 Reloading Data. !!NOT to be confused with Hevi-Shot!! My question was about the data for Active hulls, since these are no longer made.
I was told that I may sub Cheddites for Actives in both the 3" and the 2-3/4" for both the HW13 shot and steel shot.
(Toasty, or 10gaOkie, or both also told me this for a particular load, but I want to be sure for other loads, as well.)
Take care, All....
