Then I'll have brass so I can roll my own loads and chrono them.
I am going to pick up some dies for loading them, then I can experiment. A buddy of mine has some different recipes for precision loads, provided the barrel on this rifle is capable.
He is into precision shooting, he has 2 custom muzzle loaders he shoots out to 1000 yards in competitions, lol. He is blessed to have plenty of cash to do so.
