VORTEX CROSSFIRE II · 3–9×50 STRAIGHT-WALL BDC
The BDC is designed for specific straight-wall ballistics – not for every load.
This Crossfire II is a deliberately specialized SFP hunting scope for straight-wall cartridges like .350 Legend, .450 Bushmaster, and .45-70 Government.
Vortex calibrates the straight-wall BDC at 100-yd zero for holdover marks at 150, 200, 250, and 300 yd. That’s practical – but only if the actual trajectory of your combination of cartridge, bullet, velocity, mounting height, and conditions fits well enough.

3–9×50, second focal plane, 1-inch/25.4-mm tube
Straight-Wall BDC (MOA), 1/4-MOA clicks, capped turrets
3.8″ eye relief, 100-yd parallax, 18.4 oz
50-mm objective and fully multi-coated optics


Product Quick Check


Strength
Simple hunting logic with clear BDC holdover marks for popular straight-wall cartridges.


Limit
BDC is not a universal ballistic calculation. Different loads must be practically verified.


SFP
Reticle size remains visually constant; BDC subtensions are tied to intended use.


50 mm
Helps with light transmission but requires a mounting height that still fits the stock geometry.


What a Straight-Wall BDC really delivers
Vortex optimizes the reticle for typical trajectories of .450 Bushmaster, .45-70 Government, and .350 Legend. With a 100-yard zero, the BDC steps mark 150, 200, 250, and 300 yards according to the manufacturer. This assignment is a reference model – no guarantee that every ammo will hit exactly on every line.
The right practice is therefore not to blindly trust a holdover mark. First zero carefully, then check the actual ammo used at relevant distances and document the real deviation. Only then does a printed BDC become a reliable personal reference.
The fixed parallax setting at 100 yd simplifies operation but is a compromise. For a hunting 3–9× scope, that’s straightforward; those who regularly want to work with high precision at widely varying distances benefit from a model with side
parallax.

Key point: The scope makes sense if your Straight-Wall combination fits the intended BDC concept and you want simple operation. For free ballistics/turret work, a neutral reticle with parallax adjustment is more flexible.

Buy if …

You use a .350 Legend, .450 Bushmaster or .45-70 in typical Straight-Wall applications.
You prefer simple, capped turrets and a hunting-friendly fast BDC.
You will verify your specific load at real distances.
3–9× is more sensible for your hunting distances than higher magnification.



Don’t buy if …

You expect every cartridge to hit exactly on the BDC marks.
You want to frequently actively correct parallax or dial wide turret adjustments.
You need an FFP reticle for constant subtensions across the entire zoom range.
Your mounting/stock geometry makes a large 50 mm objective unnecessarily high.



Straight-Wall BDC or neutral Plex/Hash reticle?
Straight-Wall BDC reduces thinking and operation effort if cartridge and real trajectory match the reference. A neutral Plex is visually calmer but provides no preset distance marks. An FFP hash reticle is more flexible for systematic corrections but more complex.
For the hunting user working with a fixed combination, simplicity can be the biggest advantage. Those who frequently change ammunition, distance or platform should not be tied to a specific BDC concept.

Practical tip: After zeroing, create a small real BDC card for your exact ammunition. Note which mark fits at 150/200/250/300 yd and where deviations occur. This turns manufacturer reference values into a verified personal system.

FAQ
For which cartridges is the reticle intended? Vortex specifically names .450 Bushmaster, .45-70 Government and .350 Legend. Which distances do the BDC lines mark? With a 100-yard zero, Vortex references 150, 200, 250 and 300 yards. Do the marks hit exactly with every ammunition? No. Bullet, velocity, mounting height and environmental conditions change the trajectory. Your own combination must be checked. Does the scope have side parallax? No. According to Vortex, parallax is set at 100 yards. Is the reticle illuminated? No, the Straight-Wall BDC version of this Crossfire II is a non-illuminated SFP reticle. Note: Ballistic markings are reference aids. Safe shooting requires identified target, suitable backstop, legal approval and verified personal data.
