Sorry not been on here for a while, I`m afraid they are not worth anything I would shoot them off, old ironmongers and gunmakers names on the cartridges are what are collectable and worth the most
Cheers Bob
Old British paper RTO cartridges wanted, Ironmongers or gunmakers, empty or full boxes, single items, fired or full, anything considered - TOP PRICES PAID , no Grand Prix , Gastights or Foreign thanks.
First question is why do you want to load steel ? Wildfowling I guess !
Second question is it for economy ? Forget it !
Unless it is for wildfowling - dont bother - stick to lead
I must admit that I have been reloading 3 1/2" 12g loads for the last 3 years and I would never go back to lead for wildfowling as the speed that you get from these loads are far superior to lead and all the bad press about steel is rubbish, factory loads are no comparison to the homeloads you can use which have been tried and tested, factory loads are not as fast as the loads you can homeload, " dont knock
