I could use a little help. I moved about three years ago and during the move lost all my notes and targets for my White muzzleloaders. I also just completed a three year commitment, which means I will now will have a little time on my hands to make some smoke. I have a .504 Super Safari, and a .451 Super 91. I remember the .504 liked the 495 grain NEWS, and the .451 460 grain No Excuses. But, my records for what my powder charge was has been lost. I have Swiss blackpowder, but since I am starting over I would like to save the Swiss for my sidelocks. I am thinking of trying 3f Triple 7 as it is easy to procure. I am looking for recommendations for powder charges.
