Just to answer a few questions raised. As far as I am aware any of the current British Gunmakers will make you a gun fit for steel shot. Longthorne Hesketh
www.longthorneguns.com and Boxall & Edmiston
www.boxallandedmiston.co.uk reckon their guns will stand steel shot through their full choke barrels.
Yes, the London and Birmingham Proof Houses both steel shot proof guns and have done for some years. It consists of a Fleur-de-le symbol and two crowns over the letters 'SUP' for superior proof also the words 'steel shot' and the chamber length. Just looking at one my guns; a Turkish Hatsan semi-auto that was steel shot proofed in Birmingham in 2001. Lagopus.....
A question for somebody from Britain, the mother of best guns.
What are the nontoxic shot regulations in Britain, if any?
When the Prince of Wales has to shoot steel shot,,,,so will all his buddies.:)
