A lot of us on here have more than one muzzleloader. And we all like to 'tinker' with them. Just like you and your bow (I love bowhunting too)some of usstrive for perfection. I personally keep a record of all the loads from each of my MLs. Its easier for me to keep track of what ML shoot what bullet/powder combo the best. Once we find a load combo that particular ML likes it gets recorded or memorized. Then we start playing with different charges, different powders, bullets, sabots, etc. We may not improve the initial pet load for that rifle, and we can always go back to it.
