None at all.
An FEO must come across this all the time with the amount of odd ball cartridgers, Wildcats and just plane situations of brass shortages that dictate a different parent cartridge is needed for a conversion.

Yes and no, however you can not buy 6.5 x 284 amo if you have 6.5 x 55 on your FAC. So although you are correct there are a few instances where it could cause problems.

Both your points prove "calibre" should be used less to describe the rifle.
Chambering wouldnt have the confusion.
Im not sure what the last sentence should say

Actually it doesn’t (in my mind and without coming across rude)
If one would have ammunition on one’s FAC for a 308 it the “chamber size” wouldn’t matter. Or am I confusing everyone including myself?
Only because “308” almost universally means 308 Winchester (and/or 7.62x51 to some). For other calibres like 6.5mm there’s a huge range - Creedmoor, 6.5x55, 6.5-284, 6.5 Grendel, 6.5x47 Lapua etc etc so you can see why the Home Office wanted to narrow down the entries and stop the confusion by asking FLDs to list cartridges in the calibre section for ammunition.
Where it is less than helpful is in my situation but also things like 8mm Mauser which is also known as 7.92x57 Mauser, 8x57mm and 8x57IS. Do Mauser owners ask their FEOs to list all of those variations on their certificates? I doubt it somehow which means common sense might prevail, though I also doubt that very much.

The problem is the act was written by people without a scooby. The act says calibre but the interpretation is cartridge designation which translates to chambering. It’s a buggers muddle tbh

308 could mean 308 win or 308 norma magnum.
Which did you mean?
And that over zealous police officer might say " that brass says 5.56 and the barrel is stamped 223wylde".
I doubt that would even crop up, unless you've done something stupid to make them look closer.
The whole calibre/cartridge thing in our certification system is a fudge, drawn up by people who didn't know the difference, trying to control something they don't understand.

My cert is not specific for any ammo or rifle. For the ammo list, it says just .17, 6.5mm, 7mm-284, 7.5mm, .308 / 7.62mm, 270, etc.
For rifles it says just the calibre and "rifle", and for the mods, the calibre + Full Bore or Small Bore. Both sides expect the other to be reasonable in how this is implemented.
People who lack common sense and reasonableness, may not be a fit person to hold a FAC.
To take an extreme illustration, if a FEO comes along to check on things, and sees someone has a 7mm on their ticket, then shows the FAC their 30mm cannon, rechambered for 7mm, and with a rather thick barrel liner, one would expect the conversation to go badly for the FAC holder.
If you asked for a .308 and got a norma magnum without mentioning that is what you intended to your FEO, he may not be happy, and ask again for evidence of your good reason to have it.

That is my point we should talk chambering, not calibre.
Chambering cant be confused, calibre is just one measurement
Chambering can be more confusing:
5.56NATO, .223rem, 223wylde, 5.56x54mm, .223x54mm
All variants of the same thing.

Yep.
Rhen try explaining to a non-shooter why so many different chamberings use the same .224 bullet?

Don’t go there. I had a long and difficult conversation with the head FEO when I had a slot for a .22 Centrefire and then acquired a .223 Remington.Yep.

So that is more confusing than saying 22 calibre? Just in centifire that must cover a dozen chamberings of very different spec
The discrepancy is because the case has a nominal length that falls between 53 and 54mm, so either version can be used in the nomenclature and be chambered in both Finnish and Russian/Soviet rifles. (There are some military loads and chamber throat variations though as well as bore diameter differences between them.)
Given that the Finns seceded from Greater Russia in the early 20th century during the disruptions of the Bolshevik revolution, then fought a civil war between their 'Red' and 'White' factions (followed by the Soviet invasion of 1940 and loss of the Finnish Karelia region to the USSR in the 'Winter War'), the Finns hold no affection for Russia or anything Russian correctly regarding their large neighbour as a predatory and malign colonial power. I imagine that alone would make Finland adopt a designation that differentiates it from the parent version.

Good points L.
The Finns were pretty capable of using Russian rifles too - especially against Russians!
