I purchased the 330 yard second zero prism lens, and it's not even close to being correct. With my rifle zeroed at 100 yards, the second zero hits 8 inches low at 300 yards. I checked and rechecked everything to make sure that it was installed correctly. It is absolutely useless. I was shooting a 6.5 Grendel, with a 100gr Lapua Scenar bullet, with a muzzle velocity of 2818 fps.

We will be contacting you with a return label for the device. What round were you using? There are other factors involved in correcting for range. The prism offers fixed 4.3 MOA correction. Should you be shooting a subsonic round, PCC, rimfire, or other round with poor ballistic characteristics, the correction for the bullet's drop will still apply, just at an altered range. For instance, the .22 LR zeroed for 100 yards will drop 4 MOA at 130 yards. In this case, the 4.3/330 yard Second Zero will correct the shot placement for a range begining at about 120 yards and out to about 140 yards. Standard high velocity rounds such as .223 Rem., .308 Win., and 6.5 Cred. will all correct so that the range does fall inside the the 270-350 distance. That is unless you are using such a round through an exceptionally short barrel which would drastically alter the muzzle velocity of the projectile.
