Colibri's all over the place...
We are having a very unusual heat wave this weekend with temps in the 100's (108 today). I thought it would be a good time to skip on the yard work and do some target shooting from inside the garage where it is at least a little cooler. I wanted to test some Colibri's, Super Colibri's, and CCI CB Long's. I have used Colibri's before and they weren't the most accurate, but consistant enough to hit some spinners and get a decent group. Today they were all over the place. I am far from a sniper, but on my make shift 20 yard range I can consistantly get 1" groups seated with the rifle resting on a saw horse with most ammo and usually 2-3" with Colibri's. I can also hit my spinners very consistantly with only an occassional miss on the little one. Today was a different story with the Colibri's. I even had them fly off the 5" target and then the next one would hit right where I was aiming and then the next would be 3" off one way or the next. I tried both my 10-22 and Savage and it was the same - one has a scope and one has iron sights.
With the Super Colibri's it was better and the CCI's were dead on. Could the heat and humidity affect the slower rounds that much?
As far the sound level it was as I expected - Colibri's are almost inaudible with just the sound of the firing mechanism and then the round hitting the target.
The Super Colibri's are a real close 2nd place and are still super quiet.
The CCI CB Longs are a little louder, but the accuracy of them makes up for the slight noise. They are still quieter than my break barrell 1200 FPS pellet gun so they will still keep the neighbors happy. These will be my new back yard round - after I burn through the brick of Colibri's I just bought.
Any idea's on the Colibri's acting this way today?????
