7mm STW H1000 Issues Or Is It Me

In May an acquaintance sheared the bolt lugs off his rifle with what was a maximum load, that became an OVERLOAD with a new jug of H1000. He had used this powder for 10-15 years always testing new batches, without any changes. This batch was different.

Good luck

That was my experience minus the near explosion. Something very different about this batch of h1000. Thanks everyone for your replies.
