Some points I would make concerning the report of the shooter who sent his report to bushveld ........... I disagree that 7500 psi is not low pressure (for shotshells). It is! Especially so as compared to SAAMI pressure loads that are normally sold OTC. And, also as compared to period shotshells loaded with nitro for black. Secondly, the reporter seems to equate pressure with recoil. That is ridiculous. Recoil is NOT a function of pressure, as a stand alone. IF higher pressure results in higher velocities, THEN recoil is affected. It is also affected it the payload is increased and the pressure and velocity stays the same.
If 7500 psi is not considered low pressure in shotshells, what is? I load shotshells as low as 5900 psi, but just because it isn't sub-7000 doesn't mean it isn't considered low pressure. Nobody asked, but IMO, low pressure is anything from 8000 psi down. Maybe we should begin by defining "standard pressure shotshells". What are they? They are in the 10,500 - 11,500 psi range. Now ......... define "low pressure" for yourself.
