Thread: Pressure estimate for stiff extraction on new brass

Interest question only. Given the need to bump shoulders back after progressive expansion over several firings, I wondered what it would take to get the same result in one go? 65kPSI peak? 70kPSI ? I haven't recorded this in the past being more interested in what the primer pockets were doing and imagine it is more dependent on the action type than the brass so that info would be relevant.
