I watched a video last night by a guy who can be found on capandball.com. He's from Hungary and was hunting wild boar with an original Jaeger (16mm) that had been converted in the 19th century to percussion. It was his load that interested me in that he used 70gr 2F powder followed by 30gr of a filler and then finished with the patch and round ball. He said it's to improve the load but in all the videos and shooting I've been around, this is a first. By the way, the rifle looked outstanding for an almost 300 year old firearm being used in the field. Any comments or information about why using a filler will be appreciated, thanks.
