One of my hunting buddies uses a primer of 10 grains of flowered blasting powder[5F]
as a primer charge. He puts saran wrap in his quick loader over the top of the powder and puts the black 5F on that then dumps that in first pulls off the saran wrap and puts in the main charge. I warned him that he will get the remains of a cap in his face some day but he has been doing it for 5 years and is comfortable with it.
