chamber volume to barrel volume
Posted: Mon Mar 17, 2014 5:06 am
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:
