A few years back I had 11 points and decided to use them all. Booked a hunt with Jeanne horn, had a great hunt and took a big 5x5 with my muzzle loader. Wouldn't hesitate to do it again if I had points. I've killed elk with 3 different muzzle loaders, my current one being a TC omega, 348gr powerpoints, and 90 or 100grs of 777. Don't hesitate to use your muzzle loader for elk.
