I have 10% additional hearing loss in my Left Ear vs Right Ear due to one pull of the trigger on a braked rifle while shooting off the hood of a truck. I have shot other braked rifles since that incident. However, only one was mine. And it went down the road. I will work on stock fit, recoil pad, rifle weight, barrel contour, shooting technique, hearing protection, scope and scope mounts to mitigate recoil. Not a brake.
