No, it will not because your 100 yard zero is the second time the bullet crossed the line of sight. The first time it crossed was probably around 75 yards.

It will always touch it twice not matter what your zero is, as long as your scope is mounted above your bore. At your 100 yard zero it would have hit around 75 yards the first time it crossed.

Just ran a 155gr BTHP at 3300fps in Shooter, yep, about 75 and 100.

For the fun of it I tried a few light and fast and some heavy's at various and even impossible velocity. Never got anything close to 100 and 300 zeros. Maybe if your scope was a foot or more above your barrel?
