Just trimming the Noz brass on Forster trimmers I could tell it was soft. But moderate, and even minimum loads produced extractor marks. This is in rifles and loads I'm familiar with and being run through an accurate chono.
A little less than 2800fps with middling loads of H4831 and H4350 with 95 NBt's and the brass in a 243 was flowing into the extractor. Same thing with two 270's and a 30-06.
