CG don't make their barrels, they buy it at another gunmaker....that's quite bizarre for a gunmaker...like buying an Aston with a renault motor inside...
yes very good cartridge not expensive i got it here at 160€/1000, not too much recoil, not smooth as a Baschieri but not same price, try the tunet MPH 7-1/4 (fr) gold coated pellet very smooth and excellent on far target.
hello, i like your barrel they seem lighter than mine due to you don't have rib between the two barrel , look like some Kemen or Perrazzi sporting model
