First year whitetailing with the AR-10 and as of opening morning, it became known as "Jammer", because that is exactly what it does when I have multiple targets or need a quick follow up shot.
Twice, with 1 deer, made 1 shot kills and no jam.
Twice, (one big doe and spike, other 3 doe) 1 shot and jammed at 20 yards! Allbeit both first shots were 1 shot kills, I sure would have liked to have had those second shots, the follow up shots on the 2 doe would have been within 5 yards, they damn near ran me over.
This actually confuses me as this is the same rifle I used for a Tactical Rifles match firing over 100 rounds with no jams.
