I'm glad you said he played with the pan powder to slow things down. Otherwise that would be an unacceptable delay between pan ignition and charge ignition.
After much experimentation with the amount of powder in the pan and/or its location in the pan in my guns I found pan powder level across the pan below the bottom edge of the hole works best. If adjusting the pan powder doesn't improve things the touchhole needs enlargement.
