What you end up with may work but I think Carl's DECAP system is a lot simpler.

BP delay burns at about .05"/sec so it may be a little easier to trim than the BJ delays. But, I don't think we will release trim directions. I am not comfortable with 14 year olds drilling Black Powder. With every delay from 2-9 seconds available, there is not as much need to modify one to get a particular delay.
