When it comes to stump shooting; carbon arrows, aluminum arrows or wood arrows.....they will all do the following if you go stump shooting which means they will shatter, break, bend or you'll lose some of them.
Carbon arrows are not indestructible. I shattered quite a few of them when I shot a compound bow.
If you want to keep using carbon arrows, instead of going stump shooting, go "roving" instead. When roving; you shoot at a large leaf, a small stick, a pine cone, an anomaly on a dirt bank, etc.
This way, you won't break or shatter your carbon arrows. Unfortunately, nothing can prevent losing one of them.
I think I'm the only aluminum arrow shooter on TG who bowhunts with a thin walled 2212 target arrow. Since I know it's thin walled, it's not appropriate for stump shooting. I go roving with a 2212 and a backup 2212......just in case.
The one 2212 arrow I'm constantly shooting when roving, I haven't broken or bent it and it's been shot probably close to 1000 times. The arrow has been re-fletched three separate times.
Just food for thought.
