I found that this book and directions were completely mumble Jumble. If any one can make a workable silencer from these directions he must be the smartest person in the world or it was a fluke.

I am tired of reading all of those reviews who say silencers are illegal, they are NOT! You can get a permit for one (which is expensive and takes a couple months, and you must be photographed and fingerprinted) But you can do it. However, there are 16 states in which you cannot get a permit. those states are CA, IA, KS, MA, MO, and MI. If you live in one of those states and you want a silencer, MOVE! By the way, this is interesting... It is legal to own an M82A1 in every state EXCEPT california, where it is also illegal to own a silencer as stated in above list. I guess most liberals are against guns. Too bad for California residents who like guns.
Anyway, the book serves its purpose well, and as long as you live in AL, AR, AK, AZ, CO, CT, FL, GA, ID, IN, KY, LA, ME, MD, MS, MT, NE, ND, NV, NH, NM, NC, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WA, WV, WI, or WY, then GET YOUR PERMIT and make a silencer. Or buy one if you are lazy.

speeds. In a .22 rifle, you can use special subsonic ammo. Consider that the author of these 3 "how-to" silencer books wrote them while he was actually serving Federal prison time for making silencers. They were typed on manual typewriters, while looking over his shoulder for snitches and guards. So the somewhat less-polished language and drawings are forgivable.

When I saw this book (decades ago) in a friend's collection, I was inspired to make my own silencer.

There are 2 components to sound coming from a gun:
1) The muzzle blast
2) The sound of the bullet traveling at super-sonic speeds as it breaks the sound barrier!!!

A 22LR shell exits the muzzle at over 1300 feet per second. Do the math! That translates to 886 Miles Per Hour - well over the sonic barrier (500 to 700 MPH depending on altitude and barometric pressure).

You can suppress the blast, but when you do, you still hear the crack as the bullet breaks the sound barrier.

A few other cartridges that are super-sonic are: 9MM, Super 38, .357, .41Mag and .44 Mag. So how do you totally eliminate any tell-tale sound? Use a lower velocity cartridge.

As a rule of thumb, don't use a revolver; you should use an automatic pistol. The ideal pistol: .380 AUTO.

One other thing to consider. Silencers are illegal. If you are caught you could be shot or embark on an extended vacation at Club Fed.
