after reading the thread about .22lr rounds that suppose to be really quiet, i have a question. is .22lr the quietest available round ? shooting from 20" or longer barrel. doing some research, want to buy a rifle for my brother, thought it would be cool if he got a really quiet rifle, comparing to what i have, thinking of bolt action. also, what length barrel will be the queiest ?

thanks all.

Anything in 38 special with a 26 inch barrel, like a rechambered English Rook Rifle or other single shot type rifle. Shooting low powered full wadcutter pistol target rounds.

Some say this type of rifle quieter than a suppressed MP5.
And legal too.....

Lots of fun to pop bunnies with!
 
CCI CB's are the most quiet round I've fired. They won't cycle a semi-auto action but you can still use them in a semi you just have to work the bolt for each shot.
 
can you still punch paper at 100 meters with those ( CBs ) ? what does CB stand for ? and the 22 short, do they perform ok comparing to 22 long at 100 meters ?
 
performance???

CB shorts are mean't to be used at fairly close distances, I doubt that they punch paper very well at 50 meters, never mind 100. Most 22 ammo doesn't shoot very accurately at 100 meters. The longer the barrel the quieter the round is. I have some single shot rifles with 27 inch barrels and the trigger makes more noise than the fired bullet, with CCI CB shorts. FS
 
I have a bunch of CB shorts. Super quiet. and equally inaccurate. Can't really hit anything more than 25m accurately. Quieter than a toy gun.
 
well, i have one that is the quietest ive ever shot for factory rounds. i have a marlin 1892 in 32 colt. with factory ammo out of the 22" bbl it goes over the crony at 700 fps. the hammer dropping makes more noise than the shot. it is quieter than 22 CB longs
 
I remember hearing a Browning Buckmark with Carbon fibre ported barrel....although ports are supposed to make the report louder, it was extremely quiet,....I think he was using subsonic ammo in it?? which may have helped.....all I know is that I thought it was silenced.
I went to Maine and shot at a class 3 dealer and he had a silenced ruger 10/22.....the only thing I could hear was the faint sound of the action and the sound of the pop can being hit.:eek:
 
CB stands for "City Bullet" - you can shoot them in the city and nobody can hear them....lol !!! (or so I've been told...)

Disclaimer: Just kidding...

CB stands for Conical Ball

There's no way you'll hit anything with accuracy (or maybe at all???) at 100yds with a CB - even at 50 you have to aim high just to get it there.

Another quiet 22cal round is the breech cap - they work great in single shot bolt action rifles. They are effective for close range pest control and might even be quieter than a CB.

The quietest round for 100 or 200yd. use is probably the .300 Whisper or that line of cats, I'm playing around with it and high BC cast bullets of 215gr., cast hard and gas checked at 1050fps, I will try them for drop at 200 yds and then compare then to the same bullet at 1800 or so fps. This should put to rest(in my mind anyways) the 9% versus the 26% velocity loss the rags like to quote. Either way it is a deadly accurate cast bullet round with many early groups under 1/2" at 100 yds.

Subsonic .30 cal isn't nearly as quiet as you'd think. They run around 150 dB or so which is about as loud as a .22 rimfire pistol.

I did this with subsonic 7.62x39 and the drop at 200 yds from a 100 yd zero is about 40 inches.

What is the 9% vs 26% issue?
 
The story goes like this; firing the same very high BC bullet at top speed it looses 26% of it's vel. at 200yds. Firing the same bullet subsonic, it looses only 9% of it's vel. at 200yds.

I'd be willing to believe that. As velocity doubles, wind resistance quadruples. Also BC is dependant on velocity. If you measure the BC below the sonic range, it will be MUCH higher than at conventional velocities.
