Light loads, low shot charge and reasonable velocity are a must. Shooting modern factory hunting loads in any sub six pound gun is more abuse on the gun and shooter than I ever want to deal with on a high volume basis. If those type shells must be shot a light English double is not even on my list of guns to use.
