Anybody know what diameter the transfer port should be on these ?

Mine struggled to make a pellet exit the barrel at first
Breech seal was nicked from new
Added a chopped down 14mm diameter spring guide from a Remington Express, added a new breech seal, put a pair of 5p's inside the piston and upgraded the piston seal and now it's doing 2.4 ft/lb with RWS R10 7g but oddly with RWS Hobby 7g it only does 1.5 ft/lb
I sometimes find Hobby's skirt can be a bit tight in the breech of some guns, try seating the pellets a bit deeper.
Too many guns, or not enough time?
