Description
The Swift Scirocco II in .270 caliber (.277" diameter) is a 130 grain bonded hunting bullet that wants to reach out and perform. It pairs a polymer-tipped spitzer nose with a 15 degree boat tail base, giving it the kind of aerodynamic profile that keeps energy on target at distance. With a G1 ballistic coefficient of .450 and a sectional density of .242, this is a projectile that shoots flat and carries its punch well past where a lot of hunting bullets start to fade.
What Sets the Scirocco II Apart
The heart of this bullet is Swift's bonded construction. A pure lead core is chemically bonded to a thick, progressively tapered pure copper jacket, which is what lets the Scirocco II open up reliably even at lower impact velocities while still holding together when it slams into bone and muscle up close. That progressive taper controls the rate of expansion across a wide window of velocities, so you get dependable terminal behavior whether the shot is 50 yards or several hundred. Weight retention runs high, typically north of 70 percent, meaning deep, consistent penetration.
Loading the .270 Scirocco II
This is a reloading component, not loaded ammo, so you'll be seating these into your own .270 Winchester, .270 WSM, or similar .277 bore brass. The semi-spitzer nose is shaped to handle recoil in the magazine without deforming, which matters in hard-kicking rifles. There is no cannelure on this bullet, so you'll be relying on neck tension to hold it in place. A 1:10 twist or faster handles the 130 grain weight nicely.
The .270 Win has earned its reputation as one of the flattest-shooting, most versatile big game rounds out there, and the Scirocco II is a natural match for it. For deer, antelope, hogs, and even elk at sensible ranges, this bullet gives handloaders a trophy-grade projectile that rewards careful load development with tight groups and clean, ethical kills.

Frequently Asked Questions
Are these Swift Scirocco II bullets loaded ammunition or reloading components?
These are reloading bullets, meaning the projectile only. You'll seat them into your own .277 diameter brass with your choice of powder, primer, and case. They are not loaded cartridges ready to fire.
What is the ballistic coefficient of the .270 130 grain Scirocco II?
The 130 grain .277 Scirocco II carries a G1 ballistic coefficient of .450 with a sectional density of .242. That combination helps it hold velocity and shoot flat at longer ranges, which is a big part of why it pairs so well with the .270 Winchester.
Do the Scirocco II bullets have a cannelure?
No, this bullet does not have a cannelure. You'll rely on neck tension to hold the bullet in place, so pay attention to your sizing and case prep when developing a load.
What game is the .270 Scirocco II good for?
The bonded construction and high weight retention make it a strong choice for deer, antelope, and hogs, and it has the backbone for elk at reasonable distances. In a .270, it gives handloaders flat trajectories and controlled expansion across a wide range of impact speeds.
