"Barrel leading has 3 causes.\n \n\n\n\t \n\t1. Bullets too small for the bore diameter allowing hot gasses to get between the bullet and the bore.  \n\t \n \n\n\n\t2. Bullets being driven at too great a velocity.  \n\t \n \n\n\n\t3. Using the wrong lube for the velocity of the bullet. Again allowing hot gases between the bullet and the bore.  \n\t \n \n\n\n\t#1 is the problem 99.999% of the time in CAS.  \n \n\n\n\t \n \n"
