CatShooter Thanks for the explanation of velocity limits for conventional cartridges. One other question, the temperature of the gases in the barrel?
Thanks
Bill

In the throat, over 2,700° F.

The next step in velocity is two stage guns, where powder is used to drive a piston, which compresses a large quality of helium gas (which is very light), and then the Helium drives a projectile - velocities over 25,000 fps have been reached with guns of this type.

You have a number for a smith that does one of these, hoping to get a rig built for groundhog season

I can see where you are going with this though because it is tough to funnel 10 lbs. of s#$t into a 5 lb. sack!

Not when there is 55,000 psi shoving the s#$t into the funnel.

This is true lol!
