Shooting Giffards

[keith66]

A curious question for the learned on here, If you wanted to shoot an antique Giffard Co2 rifle that you owned, Not a problem in 4.5 or 6mm calibre as these can be below the 12 ft lbs limit. But an 8mm calibre will obviously exceed this comfortably, This means putting it on an fac.
If one wanted to go down that road what "good reason" would you put down on your fac application or variation?
Background is i am a member of a rifle club & about to put in for an fac, I have two Giffards in 6 & 8mm flavours & would like to shoot both of them!

Reason - Competition use.
You would like to Compete in Vintage Airgun Competitions.

Are there any for these?

Putting your Giffard on FAC will affect the value.

Im not too worried, as an obsolete antique made in 1880 it can be taken off a ticket on a simple declaration as any obsolete calibre or antique gun can.
At present you can buy an antique have it hanging on the wall when your feo comes round, apply for a fac or variation, the minute that ticket or variation comes into force it has to go live in the cabinet subject to the law. But you can shoot it. When you want to take it off do so & sell as antique.
How long this aspect of firearms law will last is anyones guess!

Is it the case with modern air rifles that when you put them on an FAC they stay that way? not sure how that works with antique air rifles.
