I shot the biggest deer of my life last Saturday 12/6/08. I shot him at 50 yards with a .50 cal muzzleloader. I found a decent blood trail about 10 yards from the point of impact. Out of fear of jumping the deer, I waited until Sunday to track the deer. I returned Sunday a tracked the deer for about 100 to 150 yards before losing the trail. I have returned several times, but am having no luck finding the deer. I think I hit the deer in the upper back below the spine. Can this be a fatal shot? Every day at lunch I watch the mountain where I shot the buck for buzzards but have not seen any flying. How long does it take for buzzards to show up? What do you guys think I should next?
