I have to agree if you want quiet than get a 22 LR with a can. If you are wanting to hunt with a 22 caliber CENTERFIRE, then it will not be all that quiet even with a can.
The post about the kids and you wanting to talk to them,,,, Well that falls short since the 22LR w/can would still be the best choice.
Even after several phone calls with JD Jones I still have yet to get on the 300 blackout band wagon.
I certainly was not trying to hurt anyone's feelings here and go back and look at my first post.
Simply said the 223 or 5.56 subsonic just does not work ! WHY????
First off the round was not designed as a stand alone cartridge It has a parent cartridge. This was the 222. It also was not designed to be subsonic round. Things happen when a bullet goes from a sonic speed to subsonic speed. Things change. Bullets also are another thing. Bullet design has something to do with this. Bullets react in different ways. Spire point round point and flatpoint are all going to act different. Along with FMJ and the various other jacketed bullets.
EXample: take the 45ACP round. First it was designed and built. THEN the 1911 was designed and built for it.
Note that the 45 ACP is subsonic from the get go. So it does not have to go through changes from sonic to subsonic. So with a can it works from the start. It is not that quiet, and there is things that have to be done for the weapon to be effective. To take an old army GI 45 and slap a can on it, you will have a nice single shot weapon that you will have to jack the slide every time.
Use a newer H&K with enhancements and the slide will operate each time. But the 45 ACP round will still do the same as it was designed to do. With or without a can.
Take an AR with reduced recoil spring and a subsonic load in 5.56 caliber and shoot it and you will still have to extract the spent round. No gain here,,, BUT,, what about accuracy or effectiveness? The accuracy is gone, partly because of velocity plays a big part in the spin and how a bullet acts at different velocities. Scratch the soft point bullets because at such low velocities they will not open up. Well that is OK since I want to save fur damage,,, I will go with the FMJ ,,, unfortunately that is not your total answer here either. The FMJ may yaw or go several different directions. The FMJ loaded to subsonic velocities WILL,, bounce off a tire (sidewall) at 10 feet. Now I am sure that most here have not been tire hunting., and I checked and there certainly is not a bounty on them. But my point is that at 10 feet, a round that won't even penetrate a tire (sidewall) at 10 feet will probably not do a lot of harm at greater distances, were most varmints are going to be. But it sure was quiet,,, Disregard the fact that at 25 yards there was no group. More like a shotgun pattern,,NO! I have shotguns that pattern way better. Oh and by the way the 22LR does penetrate at 10 feet. Hmm
For those who still insist on attempting this effort to shoot either subsonic or regular rounds and you want your gun to be the quietest possible. Then I suggest using regular ammo, and fill out the proper forms and make your own suppressor. The suppressor will need to be about 1 1/2 FEET long. This will give you the best results. I also suggest you make it out of titanium since the length is going to be so long. Otherwise the weight will be a problem. Expect a change in impact from Point of Aim adjust sights and have fun let us all know how this works for you. Speaking to those with deep pockets who insist on working on something that has for almost 2 decades, has eluded some of the best in the business.
This was not smart aleck or derogatory. But everybody has to learn. Someone here just might come up with something totally different. I am not attending any arguments.
