I've posted this question on here before, but i am still having trouble getting a good, tight pattern. I shoot .50 cal 250 grain shockwave with 2 50 grain American Pioneer sticks. I've had a couple different people tell me that you shouldnt clean the barrel after every shot with the American Pioneer Sticks. Has anyone heard the same? I heard the same thing about using bore butter as well. Any input would be greatly appreciated.
