I carry six in the quiver. Five broadheads and a dedicated grouse arrow with different color fletching. Haven’t needed more than one for an elk but there is always that first time.
7,TightSpot. 5 reg BH, 1 grouse, 1 with throwdown BH for varmints. Most used on one elk was 2. But if I happened to need more on follow up, I will have them. My motto is "NO excuses".
My first elk I shot three arrows! I shot the tree on the left then the tree on the right and finally one down the middle. I learned squatting on my haunches for several minutes then shooting while wobbling all over was not good shooting foam. Final shot was from my knees.
I carry 4 broadheads with two grouse/stump arrows for daily practice is my most common setup. I also carry additional broadheads in my pack to convert grouse/stump arrows to broadheads if needed.
I like to stump shoot and kill grouse for dinner on these hunts so I take at least 5 or 6 arrows. It keeps me sharp. ( and thats why I don’t use a very expensive arrow ‘build’ grin)
One bull decades ago I shot 3 arrows to kill him….I was getting poor penetration with the Mech head and shot location I used at the time.
