I have a new hart 26" barrel sendero contour. i like to long range hunt and target practice. I am new to a 300 ultra and have never used a brake. My questions are 1 )Do DIFFERENT brakes or designs have anything to do with accuracy or will one not differ from another? 2) If I was to paint the barrel and have a brake permantly attached to the barrel, would that be ok or do you need to have a brake taken off the barrel when to clean the brake proper? Thanks!!
