the useful fact to remember here, stateside, is that the majority of shells are being sold for use in pump guns - and autoloaders. the pump guns are okay (generally speaking) with all ammo....low pressure or high. but, many autoloaders are gas operated, and require some minimum chamber pressure level to function the action.
those of us here, who fancy old doubles are not a significant market force - and unless the pressure level of shells is clearly indicated as being appropriate for our uses....it is best to assume that all ammunition sold here is tailored to make sure that gas operated autos will cycle.
would be good to be somewhere that low pressure stuff is marketed generally.
