Preface: I have no first hand experience with cut rifling of my own. I have read and heard that cut rifled barrels last "longer" than button rifled barrels. I'm aware of the manufacturing processes for both. So my question is, does cut rifling add real longevity to the life of a barrel or is it just perceived? After all barrel life is subjective with many variables that can contribute to a short or long life span. Thank you in advance for entertaining my silly curiosity.
