just to clarify, I was watching through binos, saw no "sign" of hit, saw the impact above it in dirt, we looked for blood for 30 minutes and another hour searching hard out for several hundred yards as I watched the buck run off in the binos into the woods.. again, shooting suppressed and no audible impact (one of the "bonuses")

Not my first year of hunting and I know how to find a deer and I am NOT one of those guys who just gives up in 10 minutes..

I believe his right elbow dropped or he flinched and he shot high.. it does happen
We talked through it and did a lot of post mortem analysis.
