I have gotten some very kind advice getting into this hobby of collecting vintage doubles. One piece of advice I want to follow up on: in a 2 3/4 inch chambered 12 gauge double of say 75-100 year old vintage, assuming a gunsmith says yes to firing at all, would you try to reduce chamber pressures, if so by how much, and if so, are there any factory shell offerings that would meet the reduced pressure requirements?
