Chamber pressure of .22 rimfire
Can anyone tell me the approximate chamber pressure of a .22 long rifle high velocity cartridge? I am working on an idea and need pressure values first.

Thanks, Flutedchamber

You can trust the government. Look how well they took care of the American Indian...

Have seen numbers right around 25,000 psi quoted for 40 gr. 22LR.

Per SAAMI, maximum average pressure is 21K psi for .22 shorts and 24K psi for longs, long rifle, and WMRF.
