say the TP is 2.5x15
I'd defo open to 3mm or it just won't flow.


Normally Id say 3.2 (my PE is 3.2 x 15'and the accelerometer tests show it still being slightly too tight) but the 3.0 will cushion it a bit with the shorter barrel - although being .177 it will maintain higher pressure anyways,

and throw that weight away.

Removing the weight without opening the TP will kill the power, as its larger bore, and a tight port = way too much bounce.
