I recently purchased a T/C Muzzle Loader for Deer season this year(tierd of being just out of range with my Bow) and have hit the kill zone from 80 or so yards out with fixed sights but may need to shoot as far out as 120 yards in my hunting spot. I took a shot at 150 with my Omega scope and hit the kill zone with no problem at that distance. I'm using 250gr. Shock Wave Sabot rounds with 2 pellets at 150,is this to far to knock down a large Deer with anything put a lung or heart hit? And will the scope make it harder at closer ranges say 40 to 60 yards or will this help me drop the Deer and save myself a lot of tracking on a blood trail?
