I've had my new .22 for a few weeks and am currently shooting CIC sub's through it (old ones not the new nifty ones in the orange box).

The problem is that i seem to be getting a sonic crack out of them. This never happened with my 10/22 with the same batch of ammo.

I've tried 2 different silencers, (I know they won't take the rack out but thought it might help if some noise was due to bang)

Is it possible that with a very marginal sub sonic round the velocity may change from rifle to rifle and take the bullet super sonic?

I'm planning on trying some new rounds but really can't be @rsed to get to the shop and buy it!!

Trade it in and get a .17hmr instead, far better fun.

I always found the winchester subs teh quietest when I had a .22rf.

I have used lapua 22 sub sonic in my rifle, worked like a charm. I'm no expert but I don't think it is that stange if the round not are subsonic in all rifles. A bit of change in the chamber/barel can, as far as I know, change pressure and speed quite much.

So if you need a subsonic ammo you have to drag your self down to the shop

A Ruger 10/22 has a short barrel, maybe your new rifle is developing increased velocity from a longer barrel?

Also the 10/22 is a blowback semi-auto, not sure if this is a factor. A gas operated semi-auto would leach a small amount of gas.

CCI subsonics are barely subsonic. They occasioanlly do go supersonic. It is dependant on barrel and temperature. For ulitmate accuracy, bullets need to stay sub sonic or supersonic for each shot, all the way to the target. This is the reason that most "good" target .22 ammo is loaded slower, to ensure that they are always subsonic in every gun.

Hi All,

The Ruger I had was a Custom, so it had quite a long bore Barrell. the reason I sold it was because it was far too heavy with that barrel to have round my neck on a quad while lamping. The new rifle is an Anschutz (sp?) with a tiny carbine barrel.

I don't know anything about the mechanics of rifle making so wasn't sure if a shorter barrel increased bullet speed.

I took the rifle out on Friday night and shot about 30 rabbits and two foxes. Actually one was with the 243 but the other cub was with the .22LR. I'm really happy with how it shoots but just struggle a little with the occasional crack.

I'm going to try the Lapula this weekebnd. I have to go to the shop anyway and get the Triple Shok's for my 308 anyway.

I have the exact same rifle and use the exact same ammo! It was definately the most accurate and is also considerably less waxy than other brands!

I was warned that I might get the odd crack but never have.

Fantastic little rifle - very accurate.

1894,

Great minds and all of that huh!!!

I'm actually very pleased with the rifle and now it has had some rounds put through it the Sako Moderator is getting a little more efficient, but there is definately still a crack.

I'm gonna get some Lapula this weekend and see if they make a difference and take it from there.

I would like to stick with the CIC as they are indeed very accurate.

All things being equal, a standard 22LR will exit out of a 14-15" barrel the fastest, longer barrels being SLOWER and quieter.

I would figure that a sub-sonic 22 round would be OK with about the same barrel length or maybe even with a shorter barrel.

I have a 27" Remington and a 27" Mossberg and sub-sonics rounds exit MUCH quieter out of these two than any of my other rifles. Regular 22lr rounds are also quieter out of these two.

I cannot shoot the powderless rounds out of these, however…

Fallow Buck,

Sir, I have a couple questions for you. As the state I live in doesn't allow sportsmen to shoot with silencers, I have no experience with them. However, a .22LR is not all that loud to begin with. I would think that a good silencer would quiet an only moderately noisy round quite a bit. Do you need an absolutely silent firearm? And if so why?

Also, try some CCI CB's or CB Shorts. I have used them in a friend's rifle on a couple occasions for shooting rats. Out of a regular factory model 10/22, I don't normally get more than a primer strike and action cycle noise shooting the shorts.

Fun does not equal QUIET.
17HMR's are no quieter than a 22...

Tex,

You are right that in conventional terms the 22LR is not a particularly loud round. The thinng is though that when we go out lamping for foxes we like to pop off a few rabbits on occasion. Given our fields are relatively small a fully silenced rifle is an asset in this case because even the sound of a 22 will scare off a fox at the other end of the field if we hadn't seen him yet.

I've been out hitting the rabbits quite hard the last week, and it seems that the more rounds I put through the rifle the quieter it gets.

So it looks like the solution to my problem was to put a question on AR, and the rifke fixed itself!!!

Thanks

Indeed a moderator makes the 22lr subsonic quieter than the firing pin striking the case. The loudest noise is the strike of the bullet on the animal.

It is required if multiples are going to be obtained on rabbits. We have huge numbers of rabbits which can be effectively culled with a moderated 22LR - unmoderated really does reduce effectiveness.
