Why do you want such a powerful scope for a muzzleloader? I got the Nikon Omega 3x9x40 with the BDC reticule. I it set up for 150 gr of powder but I am only shooting 100 gr. I don't shoot long distance where I hunt but figured if I ever do I can step up the powder and having the BDC would be nice. The scope can be had for around $250 at Amazon.com.
