So I Replaced a barrel with a EABCO stainless competition barrel.. EABCO sent instructions to shoot and clean after every shot for 25 rounds before zeroing . I was taught many years ago to break in a barrel shoot and check zero then clean repeat until zero stabilized then leave a fouled barrel for that first cold bore shot it has served me well since. Having never delt with a stainless barrel before has anyone followed factory , should I stay with what I am doing with non stainless barrels or do you have a better suggestion ?
