I was thinking about it today and iirc the owner of the bore rifle rolling block in the swedish firearms forum found a case lenght of 46mm. so the pics with the new made ammo showing 46mm long brass. was there a chamber lenght of the week in the husqvarna factory? its maybe because such rifles were made from hand and only from time to time for the few conservative farmer who like to have a breech loader similar to the muzzle loader they were familar with.
