I have a two part question. I have a 1907 field grade 20 gauge with london steel barrels and am looking for shells to use and then reload. I was trying to find pressure data on what I saw advertised as English target loads in Estate shells, but could not find any data on the pressures of these 2-1/2" shells. Does anyone use these shells in their elsie? Do Estate hulls reload easily or are there better hulls out there to look for? Thanks, Rob.
