I have a 600mm barrel with an id of 8mm which works out to 30171 cubic millimetres.

Firing chamber is 100mm id of 12mm = 15085 cubic millimetres.

This is approx .5:1 (if my figures are right ) :?:

Would someone please check these figures for me.

Firing 7.5mm bb's @ 150 psi bolt action single shot.

all advice readily received. :bounce:

cubic millimetres
:D

30.17cc vs 11.31cc

That's not much for 150 psi
