Typically that is only what you hear in the movies not in real life.
I think it has been explained well enough but just to clarify we have a term in the shooting world called "Hollywood Quiet". Sonic boom and sound generated due to barrel exhaust. Two things happen when shooting a bullet. Fun stuff!įor an FYI shooting my 9.5 inch Blackout using Rem 220 gr Subsonic is LOUD without a can. Subs are fun to play with at the range and giggle when you don't hear anything, but the action cycle and the bullet hit the target. It would have plenty of kinetic energy out to 50 yards.Įither way. My ideal suppressed, sub sonic rifle would be a lever or semi-auto 44 mag with 300 grain or larger bullets. It can be done, but just makes everything harder. Which makes it harder to accurately compensate for bullet drop. Here brings another issue with sub sonic loads. A lighter faster may have a flatter trajectory, but will not carry as much kinetic energy at the same distances as a heavier arrow. the heavier arrow will hold more kinetic energy down range than a light one. Shooting sub sonic bullets at critters is comparable to shooting arrows at them. 308 bullets are not designed to expand below roughly 1500 FPS (big generalization). I know my 10" T/C Contenders was about 50 fps short of going supersonic with CCI Mini-Mags.A sub sonic bullet can kill given good shot placement and a bullet that is designed to expand at such low velocities. As I recall, typical high velocity 22 LRs take about a 12 " barrel to achieve super sonic. Hyper velocity 22 LRs such as CCI Stingers will stay supersonic until 80 yards when fired from a 24" barrel and can go supersonic from a handgun. Standard velocity 22 LRs never do go supersonic, no matter what the barrel length. Most high velocity 22 LR cartridges fired from a 24" barrel, go subsonic at 30~40 yards.

With a 22 LR ammo in a rifle barrel equipped with a good silencer, you won't hear much more than a thump sound plus the mechanical sound of the action cycling if the gun is a semi-auto. Silencers reduce the sound level quite a bit but handguns will still make a bang, mostly because all the powder did not burn up in the bore so the rest burns up outside the muzzle and makes a report. The shooter will never notice the difference. If the bullet is subsonic, all you hear is a whizzing sound from the bullet. If you just so happen to be close to the line of fire as the bullet whizzes past you, if it is supersonic, it will make a "crack" like sound as the bullet brakes the sound barrier passing by. Here's an example: When any firearm is fired without a silencer, it will make a loud bang no matter if the bullet is subsonic or supersonic. There is a huge misconception about subsonic ammo making people think it is quiet. CCI LR ammo is rated from a 18 1/2" barrel.
All Federal, Remington, Winchester, Ely, and PMC 22 LR ammo is velocity rated for a 24" barrel. Included with each specific brand and type of 22 LR is the advertised bullet weight, bullet style, ballistic coefficient, velocity, and barrel length.

I have a software package called Ballistic Explorer and it includes a very nice data base for factory ammo. They are the ambient air temperature and your elevation - just something else to think about. There are two other factors that play a part in subsonic and supersonic when dealing with a silencer. Shooting with a can indoors is even more disappointing with sounds bouncing off the walls and ceiling. You are expecting a "movie quiet" experience and that does not happen, The sound of the action when fired takes away from that - it is louder than you think. Silencers on semi auto's are sometimes disappointing. I have an early silver 22/45 with the round vents and it is a perfect host for a can. Pick up a 22/45 and you will be better off in the long run - unless you just have money you want to burn. I will use CCI Standard Velocity ammo in my 22lr rifles with 16 and 18 inch barrels.Īs for chopping a MKIV Target - do not. The feet per second rating marked on the boxes of 22lr ammo was formulated using rifle barrels - not shorter pistol barrels.

You just do not get the full powder burn in a shorter barrel - plus the gas used to work the action also takes away from the velocity. I run a YHM can on a 10" SBR 22lr AR and rarely have a round go supersonic with bulk factory ammo.
