You should always follow manufacturers recommendations.
But... I fire this stuff out of my bolt action silhouette .22 rifles and it groups decent at 25yds. Never had one stick in the barrel and I wouldnt want to be standing in front of one at 25yds when one is fired from a rifle.
BUT, you should always follow manufacturers recommendations.
: The prospect of 10 meter free pistol practice has sparked my interest. Like many airgun shooters, I have a 10 meter range in my garage. I'm very interested in using this range for free pistol practice, without the demand for additional equipment.
: An earlier thread discussed the use of Aqulia Super Colibri ammo. At Cheaperthandirt.com, this ammo is available for $12.00 per brick of 500 rounds, the lowest price I've found. But you better hurry; they only have 2500 bricks available :)
: This is what Cheaper Than Dirt says about the ammo:
: "Ammo .22 SUPER Colibri 500-Rd 20gr No Powder for .22 Handgun $12.00
: This ammo is intended for .22 handguns. Aguila .22 Super Colibri is super-quiet ammo that does not contain gunpowder but fires from the force of the primer only. Powerful and silent, great for use in urban areas. This is a 20-grain bullet in a brass case. Will break glass and penetrate hard tin cans. Velocity is 500 fps (11 foot-pounds) at the muzzle and can be lethal. This ammo works great and is intended for .22 handguns only……Do not use in long-barreled guns, as the projectile may become lodged and be dangerous (lethal) if a regular cartridge is shot as a follow up. Will not work the slide in semi-auto handguns…"
: End of quote:
: The casing is .22 long rifle with a short bullet. So it probably will not engrave into the rifling, reducing accuracy somewhat. I also don't know whether it will fit the tight chambers of some free pistols. I understand the primer contains more material than most cartridges, in lieu of the powder.
: The energy, 11 foot-pounds, is well within the capability of good quality airgun pellet traps. I presume it will also work in "putty" filled traps.
: So far, I have three concerns:
: It is intended for short, handgun barrels. So I would keep careful watch on my target holes. I think I'll buy a piece of round plastic rod, from my hobby shop, so I can probe the barrel. I would probe anytime there is a question whether the bullet exited the barrel, like when two bullets hit the same hole.
: Many airgun ranges are inside homes. My two-car range (garage) has plenty of ventilation, with all the doors open. But I wouldn't want to use this ammo indoors, without good air circulation.
: Targets are nonexistent. I'm going to make a punch, so I can cut out black circles that I can glue to the back of 10 meter targets. I can't see exhausting my laser printer toner for targets.
: So, what do you think?
