I'm getting desperate!

[Fudmottin]

I'm trying to design an integral suppressor for the MKII series pistol. I do not want to give up the velocity that the AWC Amphibian does. But I still want reasonable suppression.

I really need to know what the normal pressure and velocity curves are in a 22LR barrel.

I want to be able to have a chance at working out the barrel length to stick with and where the ports should be so that I do not lose too much muzzle velocity and still keep the muzzle pressure down for suppression.

Please help.

Thanks.
