Super Colibri Penetration!

[Freightman]

I shoot squirrels with my M69 rifle and Super Colibri ammunition and a t 40 yds they will drop one from 40' up in my big Pecan tree. So I had a phone book that needed to be thrown away, set it up and went back to the house aprox 30= yds and shot into the dry phone book. It penetrated 1.5/8" which is harder and thicker than their head ( where I hit them) so no wonder it takes them down with one shot.

And it's very quiet. Works good on rabbits too.

I laugh every time I see that avatar. Don't you let her have a taste of finger every once in a while?

[Freightman]

That is my hunting pardner she grabs them and shakes them. She also comes and gets me when she sees one.
She pointed this one out in one of my Pecan trees shot from the house 60' from the tree.

I tried shooting some of them at a piece of soft pine. They buried themselves just flush with the surface of the wood. I'm surprised that you got as much penetration as you did. I chronographed mine at 380fps out of a 16.5" barrel & a little faster out of a pistol.

Jim, Are you shooting the Colibri or Super Colibri? Very big difference in the two. I shoot them in my back yard and my across the street neighbor will be in her yard and not hear them. Alot of fun.

[Freightman]

Mine chronoed at 653/650/678 fps when my chrno worked (before it got flooded).

I see that you have a chronograph witch I don't.

Last fall i couldn't find .22 ammo anywhere, except Walmart had some cheap stuff called Thunderbolt made by Remington. I had just put a new barrel on my 10/22 and was hot to shoot it so i bought a brick.

I won't tell you it is the most accurate ammo I have (not real bad though) but it sure does penetrate through groundhogs from my deck, they seem to have a very hard lead bullet so I suspect that is the reason. I like it because I saw little or no expansion just basically straight through.

If you get the time it would be interesting what the velocity is on them and whatever tests you perform.

What is the headspace on your 10/22?
I had a lot of FTF untill I reset my headspace. I run .042. Reccomended is .040. My original bolt was .052! That is a large difference.
Now it is a tack driver, with that ammo.

Jim, Are you shooting the Colibri or Super Colibri?

I was using super colibri. I tried to find the standard colibri, but could only find the supers.

[Freightman]

I get those numbers in my other 22 a Mossberg 46B it has a tighter bore than the M69 Romanian trainer, it will also stick the Supers in the barrel so I do not use it.

[Arisaka99]

Freightman, no wonder its a tack driver, that gun is a sniper rifle trainer!!!!! My uncle has one, my cousin's husband and I were shooting, and we saw some crows out in the field, and he slid up the sight to 100, but we needed to slip it up to 125, so we missed.

[Freightman]

It is accurate here is a target, I do have a old WesternField 3x9x40 scope on it.

If you guys are talking about the 20 grain primer only 22 long bullets I have shot them for a couple of years in different guns. My favorite is in the bolt action 22 Remington 512 Sportmaster rifle. 21 inch barrel. Nearly silent when fired. Still more power than most airguns, I have chrono'd them at 550fps out of this rifle. They will bury themselves into a piece of pine at 20 yards where you can see the base of the bullet in the wood, like a dart. I use a pull through wad (just a knot on a weedwhacker line with a bit of a patch on it) to clean out the carbon soot as these are dirty to shoot and after shooting 10 or so the accuracy poops out. They are pretty accurate but the velocity is not completely consistent so they are not perfect. I use them to whack skunks when my dog corners them, and they are nearly silent, just the sound of the projectile hitting the target and the lockwork of the rifle.. MUCH quieter than an airgun with comparable power.. The key is to keep the barrel clean when you are shooting them, it seems to me. Never had one stick in the barrel but I have had some very low velocity ones that had a rainbow trajectory, and I have had a misfire before. Definitely a possibility of one sticking in the barrel so you must be aware of that when shooting them as that could get dangerous. I have shot these indoors before, but that primer smoke isn't probably any good for ya.. so I stopped unless there is some air flow. Lots of fun to shoot, you can go through 50 of them in a hurry. I shot one out of a short barrel pistol and it was surprisingly loud, after shooting them in the rifle I was thinking they would be similar, but they do have a report, the longer 21" rifle barrel must remove all the pressure of the burning gasses so there is no report to blast out of the barrel.

I bought a box of CCI CB Shorts many years ago intending to use them on rats. An old weaving mill nearby had partly collasped and the huge rat population in its basement (think Graveyard Shift by Stephen King) had spread out all around the nieghborhood.
These were some huge sturdy rats, and at first my S&W 78g CO2 pistol wouldn't penetrate their ribcage, but I switched from wadcutter to field point pellets and that did the trick. I also bought a Daisy pump up air rifle and it worked even better on the rats. I decided not to use the CB caps because I didn't want to risk damaging plumbing.

Years later I dug these out and used them when preliminary sighting in a Savage .22 rifle. they proved very quite and accurate.
Later on I used them again when sighting in a High Standard revolver, and found they worked even better in the pistol, with tight one hole groups at fifty feet.

I remember an ancient mini shooting gallery at the old newsstand when I was a youngster. I think it gave you three CB caps when you inserted a coin, don't remember if it was a nickel or a dime. The rifle was mounted on a pintle with a chain that limited its arc of fire. A crank and pulley set up moved the paper targets to the end of its tunnel.
Some kids would buy the CB caps from the dispenser and pocket them if no one was looking, then make zipguns from radio antenna tubing.

I bought some of the first Colibri that had a 20 grain bullet and no powder then they came out with the Super Colibri that has a small amount of powder for about 150-200 FPS faster

The CB rounds from Remington or CCI are much more powerful than the Super Colibri. The longs & the shorts seem to be about the same.

[Deputy Dog]

The remmington CB LR in my 541 are target grade as and they will vaporize sparrows they are a little loader than other CBs like aPCP air rifle I do get several misfires .they crno at750 fps

I love the super colibri rounds for rabbits in the back yard in the neighborhood. At 25 yards from my Ultra Light Arms, it will fully penetrate rabbits from any angle and bury into fresh cedar a good 3/4". They are the best thing for vermin control near the house

Be careful if you velocity test Thunderbolt. About a decade ago I had accuracy problems with them, tested over the crono a few and then had to stop for fear of taking out the crono.

Velocity was all over the place, and the ones hitting low on the 25Y target were doing so because they were going 500FPS slower than the rest.

Hopefully Remington has improved their stuff since then, but I refuse to buy Thunderbolt any more.

I used the regular speed Colibri to introduce my 4 yr old son to his cricket rifle over the weekend. Set up some inflated balloons for him to shoot from a seated position in my lap and later standing. He had a blast, and it was a great way to get him started with the rifle without the distraction of the noise.

I picked up several bricks of the stuff years ago when Midway had it on clearance for something like $5 or $6/ BRICK. Wish I had bought all they had!
