I recently reloaded 100 new Cheddite 3" hulls using Cheddite primers. I was looking for the maximum payload capacity for Precision Reloading's nickel plated shot, shooting for a full 3/4 oz. load of it in a plastic shotcup. I knew roll crimping would be necessary, and I managed to squeeze in .73 oz. Cheddite primers seat perfectly in Cheddite hulls, but are indeed tight in others.
I don't recall the specific recipe on the load but have it in the shop if anyone is interested. I've used a few on doves in modern made S X S guns, and they are quite impressive killers. I need to send five to Tom for pressure and velocity testing, but in use have seen no signs of excessive pressures.
