[QUOTE="Greyfox, post: 1690553, member: 10291"] IMO, this is one of the toughest questions given all the factors effecting barrel life. With one of the slower burners like H1000, Retumbo, R26, etc, and the shooting regime you describe, I would “estimate” 1500 rounds, +/- 20% when you will experience groups opening up +.5MOA, an increase in ES, and/or fire-cracking into the lands. After initial break-in, take a picture, or observe the condition of the throat with your Lyman bore-scope. Also, keep a bullet for which you have an accurate measurement of the seating depth to the lands. Give both a check every 300-500 rounds fired along with noting any major change in average group size or ES. [/QUOTE]
