The Single-Barrel, Break-Open Shotgun

[Midnitemo]

Mort back in the day when most rifles came without a thread for a moderator if you had one cut the barrel had to go and be re-proofed(expensive and time consuming)i've never shortened a barrel so i just wanted to know if tptb would require a reproof...i sometimes wonder if this kind of thing is done to drum up business for the proofhouse , anybody give me a definitive answer on lopping my 27&1/4 barrel down to 24 ...will it need reeproofing to be legal in the uk? just fancy making it a bit more wieldy.....don't care if it renders it unsellable or devalues it...was only £50 to start with.
