While sighting in and dealing with scope issues on the Marlin 780 in the last post, I tried out some Aguila Super Colibri .22 Long Rifle ammunition.
This is a powderless wonder with a 20 grain conical nose bullet.
I first tried it at fifty yards, as that is where the rifle was pointed (g). With a scope setting that placed high speed .22 long rifle rounds about an inch high, the Super Colibri hit fourteen inches lower. Worse, the group was over six inches in diameter.
Hanging a new target at 25 yards, the bullet now struck only six inches low, and shot a magazine load into three inches. Not exactly "Minute 'O Rat".
On the other hand, it's so quiet a shooter might have two or three chances before said 'rat' even notices its being fired on.
This ammunition has good reviews, but my rifle does not appreciate its charms. I know the CCI CB-Long cartridges are just as quiet, and far, far more accurate. The Aguilar Colibri ammunition is interesting, but unless I'm shooting vermin at fifteen feet I just can't see a use for it.
