Can you really compare a short-action rifle cartridge designed for a carbine to a magnum long-range rifle cartridge?
You might be surprised how the 277 Fury vs 300 Win Mag battle turns out because the Fury packs more of a punch than other non-magnum rounds, if we can even call it that.
Keep reading to discover why the 277 Fury cartridge could be the next rifle round to take the shooting world by storm!
.277 Fury vs 300 Winchester Magnum Caliber Comparison
Because I don’t believe one round is superior to another based on one factor, we will compare each caliber in nine scenarios to help you determine which is best.
Before we find out how well each round stacks up against the other in the following scenarios, let’s start with the specifications of each cartridge.
277 Fury and 300 Win Mag Cartridge Specs
Considering the overall length differences, I doubt you’ll get these two rounds confused at the shooting range.
However, ensuring you’re shooting the correct caliber in your gun is still critically important, as the 277 Fury would fit into a 300 Win Mag.
Still, it would cause severe injury or death to the shooter and those nearby if it were fired.
As you can see, the primary difference is not the bullet diameter but the casing. The most obvious starting point is the hybrid case of the 277 Sig Fury.
It utilizes a stainless steel base connected to a brass body by an aluminum lock washer.
This new rifle cartridge is designed like no other round I’ve ever shot, which makes me a little skeptical of it, if I’m honest.
Whereas the 300 Win Mag brass case is what we traditionally think of for small arms casings.
The case of the 300 Win Mag is half an inch longer than the case of the 277 Fury. It also holds nearly 40 grains more worth of powder.
One might think with more powder, the 300 Winchester Magnum would have a higher pressure, but that’s not true in this instance. The 277 Fury has a much higher chamber pressure than the 300 Win Mag.
Let’s see how the pressures equate to felt recoil of both calibers.
Recoil
Knowing how much recoil to expect is great for new and seasoned shooters. Typically, the more recoil, the more challenging it will be to remain accurate.
Most shooters, myself included, at times, will develop a flinch when firing a gun with excessive recoil, which will cause them to pull or push the bullet off target.
This is why I generally prefer a caliber with as little recoil as possible; at least, that’s what I tell myself, so I don’t think I’m a wimp!
The 300 Win Mag enters this competition with over 30.5 foot-pounds of recoil. That’s 12 foot-pounds more than a 308 Winchester and 13 foot-pounds more than a 270 Winchester, two of the closest calibers to a 277 Fury in terms of performance.
However, we’ve already discussed how the 277 Fury has 16,000 psi higher pressure, so it should have more recoil, right?
Well, that’s not the case. Many other factors influence felt recoil besides chamber pressure. Bullet weight, the rifle, and how it’s shouldered are some others.
The 277 Sig Fury has a recoil of 20 foot-lbs or so, much closer to a 308 Win (used by snipers for years) or 270 Win, which makes sense. But when we compare the 277 Fury vs 223/5.56 NATO, that 20 ft-lbs is still a lot.
The 277 Fury takes the first category because it has 10 lbs less felt recoil.
Trajectory
When we measure a bullet’s flight path based on bullet drop (in inches), we call it the trajectory. In other words, does it fly flat or need a big arch to reach the target?
A flat trajectory is what I want as a shooter because that requires fewer adjustments on my end, allowing me to be more accurate as we increase the distance.
The 277 Fury was designed to pierce near-peer body armor at long range, so we should expect a flat trajectory, especially with the kind of pressure this round produces.
When zeroed in at 100 yards with a 150gr polymer tipped Nosler bullet shot through a 16-inch barrel length, the 277 Fury drops 3.1" at 200 yards, 24.6" at 400 yards, and 43.7" at 500 yards.
The 300 Win Mag is no slouch on recoil, nor does it slouch on trajectory.
When zeroed in at 100 yards with a 150gr Superformance bullet, the 300 Winchester Magnum drops 1" at 200 yards, 6.1" at 300 yards, and 16" at 400 yards.
That’s nearly as flat as Kansas!
If you can handle the recoil, go with the 300 Win Mag for long-distance shooting or when you need a ridiculously flat bullet trajectory.
