Do any of you fine folks load Cheddite 3" hulls with Ballistic Products Stump or MG410 wads under 11/16 oz of #8 and Lil Gun or H110?

I've loaded the stump to Ballistic's specs and the shot column is quite short and it's tough to get a good crimp. I've also tried the same combo with the MG410 wads and it was slightly better but not what I'd call optimum.

If some of you do use a similar combo to this I'd like to hear about it.

Thanks in advance for you time.

Not the answer to your question, but I have tried some of the BP recipes in 16 ga and found that many of them do not properly fit in the shell.
They must develop their loads on a typewriter or computer.
