I'm lookin at a box of HSM berger VLD as I write this--all the cases are stamped "FC" not "LC" and apparently there is a difference. Anyway, you may or may not have that--in any case--so to speak--check whether or not you have primer pocket crimps. The FC stuff apparently is vulnerable to quick wear due to thin-walled primer pockets; though that may or may not be the case with newer stuff.
