I'm new to archery and I was wonder if anyone had an time frame or shot count that I should be aware of as to when to replace my carbon arrows?
When your groups start getting tighter you will start replacing your arrows when target shooting just because eventually you do knick an arrow and once that carbon is cracked i throw the arrow away. As for hunting, I would use them until you notice physical damage on the arrow. Fraying, Cracking, Splintering, etc. Good Luck
As long as there is no damage to them and you don't drastically change your bow weight, they can outlast you
As said, cracked or damaged carbon (or wood) shafts. Aluminum or alloy, generally when bent/cracked. Fiberglass the same. Yes there still are folks not shooting carbon.
