sfq,
We talked alot about your 14ga dilemma at the Baltimore show. And came up with no solutions. I don't know if your primers are available in England or Europe. You might want to ask those guys. We tried talking RST into having a special run of hulls made. He needs more interest to have his supplier do that.
I have about a dozen paper shells that take standard primers, but not enough to meet your needs.
