Greetings @Tertle,
Assuming that the loads shown in the pic are yours I would try seating the projectles a little deeper so the case mouth is in the middle of the crimping groove. I would also ensure that the cases are all trimmed to the same length as the crimp will differ from cartridge to cartridge if they are not. I would also load just 3 for a start and feed them from the mag to ensure there are no demons here to bite you later. You don't say what type of crimper you have but most need a crimping groove for best results. I once had a Martini chambered in .30-30 and the only group I shot was under 2 MoA at 100 yards (one called flyer excluded) with iron sights so the cartridge is capable.
Regards Grandpamac.
