New CCI Quiet 22 Long Rifle 22 Ammo

The center of the tight cluster was about 4 inches below the point of aim at 50 yards in my rifle sighted in zero at 50 yards with Wolf MT standard velocity ammo.

Yup, ....after 50 yards these slow movin projectiles will push the normal .22lr shooter into the art of lobbing..:D

I often can catch the bullet in its path of flight. Still at 40 grains it's up there with the high-power pellet rifles along with a pleasingly low report.

Was :) when I found out my 10/22 automaticaly converts into a 40 yard air rifle..

After reading the posts and checking a few other sources, I think the CCI Quiet rounds I purchased at WalMart were miss priced...And I intend to go back and question that. I also tried the round in an older bolt action with a 24 inch barrel and it lived up to it's name...extremely quiet with the sound of striking the trap overshadowing the report. Accuracy testing will have to wait till I am at the range.

I will vouch for the fact that this ammo really is quiet out of a long rifle. Out of my 24 inch barrel, the firing noise was dominated by the hammer clicking. People next to me remarked "you actually shot that thing?" The loudest noise it the bullet smacking into the target.

It will still most likely kick an air rifle's butt at 50 yards, especially when you factor in wind drift. That 40 grain slug will just about ignore a crosswind that would blow a 7 grain .177 cal or a 14 grain .22 cal pellet right off the paper at 50 yards.
 
ehhhh, I wouldn't go that far.

Modern .177 pellets up to 10.2 are close to super sonic. So they have 1/2 the time to target of the quiet rounds, so the time exposed to the wind is about 1/2. Plus the cross section exposed to the wind is less with the smaller diameter and shorter pellets.

I know that I'm still deadly on bunnies and tree rats at 50 yards with a break barrel .177 using 10.2gr pellets.
 
Wind drift isn't determined so much by time needed to reach the target but by how much velocity is lost on the way to the target. The faster a bullet slows down, the more the wind drifts it.

Take a .22 caliber 40 grain bullet with a BC of .13 going 710 fps at the muzzle and a 10 mph crosswind.
50 yards 675 fps 0.9 inches wind deflection
100 yards 643 fps 3.6 inches wind deflection

Now compare that to a .35 caliber 65 grain round ball from a muzzle loader, BC .049

Muzzle velocity 2500 fps
50 yard velocity 1703 fps wind deflection 2.25 inches
100 yard velocity 1125 fps wind deflection 10.91 inches

Notice how rapidly the roundball with it's .049 BC lost velocity and how much the wind drifted it.
Bullets that slow down like balloons drift like balloons.

Now, speaking of air rifle pellets, the best BC I have found for .177 caliber pellets is .025 for a 10.6 grain pellet. Let's assume your air rifle shoots it at 1200 fps (very unlikely, those advertised velocities are achieved with the lightest pellets available) Same conditions, 10 mph crosswind.

Muzzle 1200 fps
50 yds 804 fps 5.9 inch wind deflection
100 yards 619 fps 21.5 inch wind deflection
 
wont expand the casing at all, just falls out of the extractor in my 10/22 unless the ejection port is pointed at the ground before pulling the bolt.

not bad, no noise to it. just hear bullet hit downrange. more accurate then the 22 longs.
 
Do these have any powder in them or do they just use a primer like the Aguila Colbri's do? I suspect that they've probably got at least some powder in order to propel a 40gr bullet as fast as they do. Also, Aguila recommends Colbri's be used only in handguns due to the possibility of a stuck bullet (though I know many people who use them in rifles without issue) but I notice that the CCI Quiets carry no such warning (at least not that I can find on their website).

They carry a small amount of propellent. As for squibs, no reports I've heard of.

CCI's Quiet ammo is specifically designed for longer barrels to achieve the low report levels, so there shouldn't be a problem, as long as the firearm's barrel is clean/ maintained.

As for Aguila's Colibri ammo. I've shot the plain Colibri and Super Colibri through my 10/22 18.5 inch barrel with no issues.

But i suspect there's a good chance of squibing in the longer barrels, especially with plain Colibri.
 
I just started shooting cci .22 shorts out of my ruger 10/22. It is as quiet as a pellet rifle. I love plinking with it.

I talked to Brett Olin of CCI at the 2012 SHOT Show and he stated that the Quiet-22 was safe to use in long-barreled .22 rifles.
