I have the Z5 3.5 -18 X 44 on my 300 Win. I'm sorry but I don't have my data handy. I believe my 180 Accubond is at about 2980 FPS (200 yd zero with 26" barrel, 10 shot avg. through chronograph) and has the Outdoorsman custom turret on it. I run out of turret at 725 yds. I have enjoyed this scope. It seems to track well and is very light. The glass is good stuff especially for a one inch tube. This is the only Swaro scope I own but do notice the exterior finish is tough as nails when compared to some of the other scopes I have.
