I agree with the other guys that it sounds like your arrows are stiff, but check the brace height first. You didn’t mention what brand or model, but something around 8 inches will get you in the ballpark. If it is lower than that, it could be the cause of your feather wear. If the brace is OK, then it is probably the stiff spine. You can go to a less stiff shaft or a heavier point. I recommend trying the heavy point first as it is a cheap way to verify a too stiff spine.
