The only powder that shoots better with out swabbing is Blackhorn 209. I have quite a number of guns and the only other ones that shoot well with out swabbing every shot is traditional with BB. Lee
Sabotloader has proven that you
can shoot BH out of the 700MLs but I'm just not comfortable with it yet. He must have a stronger spring in the firing pin than what I do. I still get too much blow back for my comfort. I can shoot 120g of 777 and not have an issue with blowback. But 100g of BH and it recocks the bolt and the primer comes to pieces and even once out of the action.
It will flat shoot 777 so I will just keep shooting it in the 700 and leave shooting BHto the Genesis.
