[QUOTE="gunnar andersen, post: 1939135, member: 99774"] My Teslong borescope shows some severe cracks across the lance, and reading here I identify them as "heat cracks". This barrel is from a 7 mm Blaser with 1000-1200 shots through (poor shooter) If this is heat cracks and deterioration of a barrel, do any one know how to prevent this in a new barrel?? Pictures I have seen here is mild compare to mine. Some of the worst cracks is before the mussel?? Now further after have view other pictures more closely from others, I do think the cracks across the riflings is left tool marks, this is a Shilen barrel. The barrel was shooting great for the first 800 shots or so with these cracks so perhaps I have other issues. I have now had a look at some of my other rifle barrels, they do not show these crack across the riflings it must be how the Shilen barrel was made?? [/QUOTE]
