Shoulder Bump?

[RRP II]

With 6.5 Creedmoor fire form brass I have set my FL resizing die to bump the shoulder back .002 from that fire formed brass. I have some brass (30) prior to setting up the FL die correctly that has the shoulder bumped back from .006 to .008, is it safe to fire this brass with this much shoulder bump and hope the firing forming will bring the should back to within acceptable limits or should I trash it and move on? I have been using the Innovative Technologies shoulder gauge for measuring the shoulder bump which is a very worth while investment if anyone is looking for such a tool.

Shoot away.

You're fine. If you're worried about starting a case head separation line, just put a little Imperial sizing wax on the front half of the case wall before shooting. This will let the case move back some and not force all the stretch in the area just ahead of the case head. At the amounts you indicated this really shouldn't be an issue. I've seen some factory ammo that's "shorter" than that.

Thanks guys for the fast response. Yes I was concerned about the chance of a head case separation.
