    Musgrave 243 with oversize chamber - fire forming tips to avoid case stretch?

    Hi, I have a 6mm/243 with a slightly oversize chamber (headspace on fire formed brass measures 41,02mm as apposed to the more regular 40,96mm). When firing cases, the additional headspace leaves stretch marks on the cases (similar to excessive pressure). I am worried that these cases will...
