Long time lurker...time to add a data point.
First off I have followed the thread since the fist few posts and have read it in entirety a couple times over the last couple years. I update the thread daily during hunting season also.
I typically hunt ridge areas and fields in NWGA. Shots range from 10-400yds. I prefer to carry my 10.5" 300 Blackout suppressed SBR, 1-4 scope, with Barnes Tac-Tx as it is easy to carry, does not require ear pro and has never let me down. It has also has yet to require a tracking job more than 30yds. I am comfortable with a 250yd shot with this setup.
I am a AR15 hobbyist. I like the ergos, Im comfortable with one and I shoot them often from 10-300yds in various positions at my local rifle club. For all the reasons pointed out in this thread I gravitate towards 223/556 but I still hunt with my 300BO.
The new area I am hunting this year is so thick plus leaves have been late to fall that my Vortex 1-4 just isnt doing it.....I missed a couple doe opportunities recently. I did not have time to swap optics so I took my 10.5" red dot equipped 556 house gun with 73ELDs out on Christmas eve morning to get those does I missed the previous outing.
Well less than an hour in the 180lb +/- 7point we call Loki that Ive been watching on camera for 6 months comes in to about 40yds stopping in one of the very, very few shooting lanes available in this spot. In the 10sec transaction he took a 73 ELD in center of chest, turned with tail down and slowly trotted off. I felt like it was a good hit and thought I heard him crash down the North (steep) side hill out of sight. I waited an hour to get down.....alone with my thoughts.
Once I got down to find him I found ZERO blood or hair.....nothing. I was sick. Looked for 1.5hrs before calling in the dog and help. Dog found him in 5min, buried in a ravine head down 30yd from where he was hit. We drug him an hour out of the ridges to where a vehicle could access for the remaining haul.
We do gutless processing, were wore out and were in a hurry to say the least so no necropsy pics. Opening him up he was full of blood, I assume the heart was destroyed and pumping it into the chest cavity.
Soooo.....It work and worked well at killing a mature buck. Maybe better than my beloved barnes 110s. It did not leave any blood to track and in this area thats a problem without a good dog. I will try the 77TMK before our season is over
