CB's

I've been shooting the CB shorts for years and have killed MANY, MANY critters with them. Everything from chipmunks to red fox and more than anyone would ever believe. The CB's are hands down the best home pest/critter control round ever made.

thanks for posting the results. even though I knew they were potent, that added info is good to know.

 

I have used them to roughly sight in a scope I just mounted before going to the range, firing into a 2x4 with a 1" orange stick-on target as POA. It would consistently penetrate 1/2 way into the board.

 

Mythbusters did an episode in which they shot a 9 mm pistol, a centerfire hunting rifle, and a 50 BMG rifle into a swimming pool and measured the penetration distances. The slowest rounds (9 mm) had the greatest penetration.

Would be interesting to compare CB's with Quiets, both rated at 710 fps.

 

Anybody remember a guy who went by the name "Digital Dan" who used to sneak around the Florida woods at night, getting really close to wild hogs and shooting them in the head with CB caps? He posted a lot of pics on various gun forums around the net.

Cci cb longs

much more accurate and dont fill the .22LR chamber with carbon and lead crap. Same price.

Actually...... from my rifles, the CB Shorts grouped better and were more consistent, velocity wise than the CB Longs.

The likely reason is that the miniscule powder charge works better in smaller confinement.

I had no problem shooting .22 LR afterwards.

Lower velocity means deeper penetration (up to a point!)

In the late 19th century (1800's) into the early 20th century we found for Africa hunting the magic velocity was about 2150 with a bullet with SD of .300 up to .350. When velocity was jacked up to 2350 bullet failure and over mushrooming caused penetration to drop. Shallowest penetration of the big boys was with a .460 Weatherby 2,600ft/sec and the best was with the SAME bullet down loaded to 2150ft/sec in the same case.

A .22LR target velocity solid will completely penetrate a whitetail skull (in and out) where a HVHP will not. (Both kill deer like lightning though!) The point is the penetration. If the bullet makes it into the brain the deer dies period.

The most reliable medium in all of Africa is the 9.3x62 286gn bullet at 2,300 - 2350ft/sec with ANY bullet. Even cheap softs stay together and penetrate well. Most of our shooting is at an average of 75 yards as we prefer to 'get closer'.

 

If anybody here hasn't already, I HIGHLY recommend watching some tube videos by 22 Plinkster. His trick shots aren't only impressive, but he also does a lot of penetration experiments with various rimfire ammunition. Check it out.

 

Coons, crows, squirrels, rats, .... Did I miss any species?
CCI 22 CB short from a 24" rifle barrel sounds like a BB gun if it hits a soft target.

 

Coons, crows, squirrels, rats, fox and skunks...

 

How similar are the Colibri rounds from Aguila to the CCI CB ammo?

 

Similar in appearance but not nearly the same. Colibri uses a 20 grain bullet with a stated muzzle velocity of 420 ft/sec producing 8 ft/lbs of energy at the muzzle. The CCI CB .22 short uses a 29 grain bullet with stated muzzle velocity of 710 ft second producing 32 ft/lbs of energy at the muzzle.

Colibris are a fun round for quiet backyard plinking. The CBs are a much more (relatively) potent critter gitter.

Thanks.

How long of a barrel is it safe to use with the CB shorts? I have read that people have hung colibri's in rifle barrels.

Academic anyway. Can not find any right now. Will keep watching.

 

Hi, I've shot bricks of the standard Colibri through 16" to 24" barrels with no problems as long as I ran a lightly oiled patch through first. They don't like dry bores. If one does get stuck you can push it right out with a cleaning rod. Leaving a bullet in the barrel is a reasonable fear but it's pretty obvious when it happens. If in doubt eyeball or blow down the barrel before putting the rifle away.

The Super Colibri is just as quiet and readily available. Same bullet, 590 fps and 16 ft/lbs at the muzzle.
