I'm firmly convinced you could damage a rife by shooting too many rounds of these systems, but I'm planning on being very conservative and shooting only enough to smooth out the rough spots as evident from the lead slugging bullets that are pushed down a greased bore. My rifles shoot good already but I feel that conservative use of the Neco system can't hurt and will make cleaning up easier. I'll keep everyone posted on my experience. Just ordered the Neco kit today. I will also be keeping a close eye on the throat and any lengthening that takes place.
