Took the Knight UL out to the range today to work on 3-shot load groupings with BH-209 at 90gr, 95gr, 100gr, 105gr, and 110gr. All shots were at 100 yards using Harvester green sabots with their 300gr, .50 cal white Scorpion bullet. Used CCI 209 primers, but they seemed to get jammed in the bolt after firing.
Gun seems to really like 100gr with that load. Used to shoot 777 but never got that consistancy with musket caps.
Any thoughts on what might be causing this issue?
