roll caps give enough fire for consistent ignition????,I use the .005 " brass sheeting.
Attached is a photo of a tin of my home made caps.
These were made with a #11 cap maker and paper roll caps I punched out with a small hole punch.
To secure the explosive dots I used duco cement. A single drop per cup.
If you have any Questions about them I'd be glad to help with what has worked for me.
Fire away!
