psi-damage

Unread postAuthor: )DEMON( » Fri Apr 21, 2006 3:09 pm

I am trying to find a psi to damage relationship for a pnumatic .eg if you pump your gun up to 'so much' psi ,it will do 'so much' damage.
please post how much pressure you had in your gun and how much damage it did to what you shot it at. thanks.

I had a simple over-under pneu with a 2 foot chamber and 3 foot barrel. It was my first pneumatic, been occupied by combustions lately. Pumped her up to 110 psi and shot a brass ball at a wooden well yard decoration. Blew a fist sized hole in the front of the well.

use the ggdt for this kinda stuff, it gives you muzzle velocity and engergy...

you gotta count chaber volume, barrel length and size too, valve opening speed... etc

I don't think that you will be able to come up with a true ratio between the two. There are many factors including:
Chamber volume
Barrel volume
Valve type and size
Ammo shape, weight, size
etc.

i dont really think theres just a psi to damage relationship, i could have 300 psi behind a ball valve, and do more damage with a piston valve at 70 psi, theres alot of factors to consider.

one of my best shots was shooting a 1/2" bolt through a steel lawnmower cover at only 50-60 psi.
