First thing that I noticed is that it is fairly heavy but not as bad as I first thought it would be. But getting the bipod or shooting sticks would be a good thing.
Shooting the TAC 15 is an interesting experience. With so much stored energy the limbs the TAC-15 has a noticeable kick almost as much as the AR15 only with out the sproing sound. (for those not familiar with AR 15 it has a spring recoil compensator in the stock that makes a sproing sound when the gun is fired)
At 20 yards the TAC 15 is good, the bolts were less than a 1/4" apart and I wasn't even really trying for accuracy. But the TAC 15 doesn't really shine till the ranges get longer and the TAC 15 really shines at LONG range. The TAC 15 is capable of MOA accuracy at 100 yards and acceptable accuracy at 120 yards. The TAC 15 is capable of being more accurate at 100 yard than some rifles I have.
After trying it out I see why it has to use the special bolts. The bolts for the TAC 15 are long and heavier than I expected but they have double thick carbon walls to make them stiff enough for the bow.
Ok that's about it for now.
