Welcome to the dark side Andy
This guy’s worth listening to Peter, he knows his stuff.
I recently fitted a 17” (432mm) barrel to my TM1000 (16J) and it is unquestionably shooting better. Whether that’s because of the reduction in length from the standard 19” or whether it’s just a better barrel, I don’t know.

Brian,
From where did you source your barrel? Custom air rifle barrels does not seem to be too easy to come by.

Hi Brian,
Great link. There is so much to learn, so what is "Polygon Rifling" as compared to other riflings? I guess it is not the method of rifling? I must also find someone to machine the barrel when the time comes.
I'll let you know if I need export help

The shorter barrel is - the more accurate will be rifle.
But barrel's length should be as short, as it's required to get the necessary power.
Usually barrel's length is something nearly 500mm for 20-23J.
