There's two word i'm not sure to realy understand:

1/ The Breech port : is it the same thing that the Transfert Port ?

2/ The Barrel Port : is it the hole in the barrel witch communicate with the transfert port ?

3/ If someone have good notion in French, could you confirm me that "advice" mean "valeur conseillée" ?



Thanks by advance !



NOTA: I'd like to tell you that i open a Youtube channel called "OCCITAN'S COMPATTO" where i made and post lot of technical video about my Brocock Compatto Target.
So, if you're interested, it's here: https://www.youtube.com/channel/UCM2uwCpOKUpA6nQfy3CAprA/videos

Yes, the Breech port is the port that goes from the firing valve port to the barrel port. The barrel port is the hole in the barrel that the air from the breech port goes to before entering the barrel and pushing the pellet out. 

In the chart you port, I'm pretty sure they mean "Advised", vice "Adviced", but for this purpose it means about the same thing. One port size is the original, or "as built" port size, and the next is what is "recommended" port size... So yes, "adviced" in this case means "valeur conseillée".
