Muzzleloader Hunting

Yesterday morning was my first time ever hunting with a muzzle-loader.  Primitive Weapons season opened in Georgia yesterday.  My brother-in-law loaned me one of his, an older flintlock style with iron sights.  The only thing missing from my hunt was some buckskin clothing and a pair of moccasin boots!
The sun arose upon a beautiful morning overlooking the pea patch.  I have seen many deer on camera and several from the stand on the other end of this food plot so far this season.  Around 8:30 yesterday morning I was looking down the patch to my left.  Several hundred yards to my right, someone let off a couple rounds from a shotgun.  As I instinctively turned my head, I looked down and there he was.  A young 8 pointer I had been seeing on camera was standing less than TEN FEET from my stand.  He looked in the direction of the shots and then right back at me.  Two seconds later he wheeled and high-tailed it in the direction he from which he came (which was also the trail I had walked in on earlier that morning!)  He didn't run too far, but just far enough to be out of range and a couple more steps put him out of view.
About 15 minutes later I was texting my brother-in-law about it when I looked up from my phone and down the slope in front of me.  I noticed something out of place, and then realized it was the front shoulder, leg, and chest of a good sized deer.  He stepped out from behind the tree and immediately began leisurely heading away from me.  It was another 8 pointer but with a larger rack and a good bit bigger body.  He was about 75 yards away when I first saw him, just beyond what I believed at the time to be the range of the weapon I was using.  I didn't have any kind of calls with me, as usually this time of year the deer don't seem to pay any attention to them.  I would have liked to have had something to try to turn him with.  I tried a mouth grunt, and that stopped him for a couple of seconds, but didn't turn him.  From now on, I will be carrying my pack with all my gear even in early season!  I hope to have at least one more encounter with this buck this year, hopefully an up close and very personal one.
I didn't see any more deer, nor any from the stand that evening.  My father-in-law and nephew did get busted by one as they were climbing down at dark.  He blew at them and ran off.  About ten seconds later, he blew a couple more times.  I heard him all three times, but the way the sound carried through the bottom, I thought it was down in front of me where my brother-in-law was just cranking up the Mule.  I thought at first that the deer had busted him.
Before we headed out for the evening hunt, we ate fresh fried fish and a bunch of oysters off the grill. 
Not too bad a way to start and end my first day of hunting with a muzzle-loader.  It won't be my last, for sure....
