It does not look like the barrel was bulged but you dont know until you get the bullets out. Trying to drill the bullets out without touching the inside of the bore is extreamly hard and slow (meaning expensive), and you don't know if the barrel is bulged or not until its done. If it is 2 or 3 bullets I will try it but not 7. It is cheeper and faster to machine a new barrel.
