The Holland & Holland cartridges listed above, I can vouch for them being superb products.The Light Load is a really wonderful cartridge, loaded in English size 7 it will break clays, shoot pigeon all day long without adverse reaction to recoil. The price quoted in the advert is extremely cheap, I am sure that I cannot by them for the equivelant price here in the UK.
I do feel that RST can provide cartridges to suit your needs. I met the owners/vendors at the Vintagers and found them to be most gracious, knowledgable and helpful.
