Now, I wouldn't bother with it unless I had a reason to try.and what I think is the right gun. Velocity so slow that there are reports of it getting stuck in some long-barreled 22s! Last week, I found some online and ordered it to try, it's supposed to arrive today. It's a 20gr, conical bullet propelled by the primer alone, velocity given is 500fps the muzzle. On a related note, about 4 months ago, I read about an Aguila 22 ammo called 'Colibri'. **EDIT~allot of these 'Quiet'offerings lack the punch to cycle an autoloader. I haven't found them to be as consistent, or anywhere near as accurate as ammo in the 1050-1070fps range.but for plinking, close range shooting/pesting, teaching kids to shoot~it's great stuff. I've tried CCI CB Long, CCI CB Short, an CCI 'Quiet-22' and Remington CBee 22. The longer the barrel/the quieter they will be. As other have stated, some are more quiet than others.but your barrel length plays a roll as well.

I think what you're asking about is some of the subsonic ammos that are super-quiet, and on the slowest end of the spectrum.not just any subsonic rrect? If so, the quick answer is YES.they are substantially more quiet than ammo types in the 1050-1070 fps range, and WAY more quiet than high-velocity. My best bolt gun shoots 1 type of high velocity ammo well.but about 5 subsonic ammo types well.and I think I've tried nearly everything but match-grade stuff! Subsonic ammo is widely considered to be more accurate than supersonic/high-velocity ammo as a rule, and for the most part.that's been true in my own experience. One ammo type (CCI 'Standard Velocity') is named for this, and no 's velocity is listed 1070fps. It's why most ammo falls just under the 1,100 fps range, or nicely over it. In terms of what you buy in stores.and how it's discussed in plain terms, subsonic ammo is often referred to as 'standard velocity' and supersonic ammo is referred to as 'high velocity'. 'Subsonic' (=slower than the speed of sound, or, less than about 1,100 fps) doesn't mean it's quiet, rather, it lacks the dible 'crack' that high velocity (=supersonic) ammo has. I think it's worth adding to the discussion that 22 ammo basically falls into 2 categories~subsonic, or supersonic. However, I'll copy what I posted in another, similar thread on here recently as 'subsonic' encompasses a wider variety of ammo that allot of people seem to realize I'll report back when I get a chance to group the biathlon ammo.Quick answer~CCI 'Standard Velocity'. Now that's after warming up on the 3' spinner at the same distance.Ĭertainly not conditions conducive to testing the grouping accuracy of a round, but for me, the 'practical' accuracy of that particular round is very good. I aimed 1/2' high and 1' to the right of the target and hit it 10 out of 10 times. I was shooting at a 1.5' round spinner target at 75 yards, using a telescopic, non attached Cabelas bi-pod and shooting from a seated position. The temp, (as it hadn't started raining yet), was 38F, but the wind chill was a might colder.

At that, I almost got knocked over by a gust as I was walking back from setting out my target. I have a sprained ankle, so I'm walking kinda careful. The wind was rigth to left at a constant 18-20mph, with gusts to well over 30. I'm waiting for one of those nice crisp, clear 15-20 degree days to test this ammo.Īs to CCI SV, which is my favorite, I was shooting some this afternoon. It gets rather chilly up there.Īs to 'getting colder', it's currently a balmy 42 degrees and raining. My neighbor is the range safety officer at the Auburn Ski Club biathlon range, which is located just west of Boreal Ridge, up on the summit of I-80. She said she's also got some CCI Biathlon ammo somewhere that she'll bring over. The ammo she gave is from a stash that's at least 10 years old, but has been very well stored. stay warm and please check back in with any updates you may have. Im not sure who you are trying to kid right now saying, you are waiting for colder weather but i lived out that way and traveled through truckee many times to know better lol. if you think of it, ask that friend of yours what ammo they use in the freezing weather for good accuracy.

D read your thread and it is where i got the idea of fiocchi sm340.

Are subsonic rounds more accurate
