I got the chance to fire off a few rounds of CCI Quiet .22 LR yesterday. It's a 40 grain lead round nose bullet at 710 FPS. Last month I got 2 bricks of it from Midway.
From my daughter's Savage Rascal with a 16.25" barrel, it makes less noise than a high powered spring piston air rifle. Remington CBee loads are louder.
From my Beretta 71 pistol it's a lot louder and sounds like a gun. It did not have enough oomph to cycle the action. I'm looking forward to trying it in my Ruger 22/45 with suppressor. I'm hoping the can will add enough back pressure to allow the gun to cycle.
I didn't test for accuracy as we were in a friend's yard plinking.
If you can find some and you have a gun that shoots it well, the CCI Quiet should make a good load for discrete pest control or small game hunting.
CCI Quiet .22 - RANGE TESTS OF 9 Feb 12
ReplyDeleteChronograph and accuracy data follows:
High Standard Sentinel REVOLVER, with 4 inch barrel and 0.008 cylinder gap:
First shot fired in dirty, fouled training gun stuck in the barrel!
Drove out stuck bullet easily. Cleaned, oiled, tried again.
Point of impact 1 inch below sights at 7 yards.
Avg. velocity 505 fps, lowest (which got out the barrel) was 372 fps, highest 628 fps, extreme spread of the 9 of 10 shots which actually exited the barrel was 256 fps, with a standard deviation of 87 fps.
If using this in revolver start with clean, lightly oiled bore.
9 Feb 12 function fired 50 more rounds in revolver with no malfunctions. Bullet in bore appears to be a rare event, but you need to be aware that in revolvers a loose cylinder gap may interferes with being able to build enough pressure to acquire enough velocity for reliable bore exit.
High Standard Model "B" semi-auto pistol with 6-7/8" barrel, typical of "Survival Ruck" guns we might use:
Point of impact 1 inch below sights at 7 yards.
Avg. velocity 638 fps, 25 standard deviation, extreme spread of 10-shot string 82 fps.
Does not eject empties or cycle action. Feeds smoothly when cycled manually.
Quiet shooting indoors without earplugs, about as noisy as firing standard velocity .22LR in a rifle.
Accuracy test at 25 yards, sandbagged, ten shots in 3-1/2" vs. 1-1/2" for CCI Blazer HV.
Accuracy test at 50 yards, sandbaggged, ten shots in 6" vs. 2.5" for CCI Blazer.
Ruger M77/.22 bolt action, 20" barrel.
Point of impact 5" below zero for Blazer HV at 50 yards.
Avg. velocity 713 fps, 28 standard deviation, extreme spread of 10-shot string 114 fps
Accuracy test from sandbags with 4x scope ten shots 1.8" at 50 yards, vs. 1.2" for Blazer HV
Point of impact at 50 yards 5" below zero for CCI Blazer high velocity
Accuracy test from sandbags with 4X scope ten shots 4.7" at 100 yards vs. 2 inches for Blazer HV
Point of impact at 100 yards 18" below that of CCI Blazer when zeroed at 100 yards.
Remington Model 511 bolt-action .22 with 24" barrel:
Shooting outdoors 50 yards at 6 inch pistol gong with open iron sights, hold bead at top of gong with open sights to hit. Avg. 688 fps, 48 Sd for 10-shot string, extreme spread 157 fps. Very quiet in rifle, like a CB Long.
When introduced in 2012 this was an affordable ($30 per 500 rds) low noise, evader's or trappers load for short range. These have replaced CB Longs in my inventory. Each ruck containing a .22 cal. firearm gets a box. I recommend each gun you intend to use these in be test-fired with a full box to assess reliability, point of impact with existing zero, and accuracy at realistic small game foraging ranges from 25 to 50 feet.
This load seems to do best in barrel lengths at least 6 inches.
Velocities were erratic in revolvers and rifle barrels of 24 inches or longer which increase bore drag. Comparison of velocity test data with other CCI .22 LR ammos:
