First off,I have always hunted with .029 because the fibers of old weren't as bright as the fibers of today.Well,I bought a sword with .010 pins for taget shooting and had reservation about trying to hunt with them but thought I would test them out just to see what I thought.Glad I did because I have NO PROBLEMS seeing them in the lowest of light conditions.
I have a huge worn out spot on me Morrel target and decided I would try to hit the center at 20 yards right at dark.I was pleasently surprised how well I could see the pins.
I used the light on it's lowest setting for 3 shots and didn't use it all for 3,I couldn't tell any difference in impact.
Here is the group,pretty good considering it was dark and I was aiming for center instead of at a spot.
The pic was taken with my cell phone and the flash on.
