Like the hot desert wind of the same name, Scirocco II bullets are powerful and unrelenting.

 STORY AND PHOTOS BY PHIL MASSARO 

The .338 210-grain Scirocco II.

I had been frustrated with the terminal performance of my .300 Winchester Magnum, as the cup-and-core bullets – which flew very well when punching paper – were giving too much expansion when used in the New York deer woods. I needed a stiffer bullet, yet wanted to take full advantage of the flat trajectories and wind deflection characteristics of the spitzer boat-tail bullets. I did a bit of research, and found an advertisement for the Swift Scirocco II. The ad copy touted a newly engineered jacket, which would improve the accuracy of the bullet. I ordered a box of 100 .308-caliber 180-grain Scirocco IIs, and headed to the bench. I had developed a load for this particular rifle that gave just under minute-of-angle accuracy, so decided to start there (it was well below maximum), and see what the new bullets would do.

I firmly believed the first three-shot group was a fluke – my wiggles must’ve accounted for my waggles – as it printed just under a half inch, but when the second and third did the same thing, I was a convert. They gave good velocities out of my 24-inch barrel – 2,965 feet per second, to be precise – but would they perform as advertised in the field?

The .338 Winchester Magnum is well served by the 210-grain Scirocco, giving the cartridge a flat trajectory and good terminal ballistics.

You see, the Scirocco is a bonded-core boat-tail bullet, with a very thick jacket and a black polymer tip. It is designed to not only fly accurately – which it proved to be true – but to give the consummate blend of expansion and penetration. Many cup-and-core boat tails have a tendency to have the copper jacket separate from the lead core upon impact at higher velocities, and that didn’t make me happy. The Scirocco’s thick jacket is chemically bonded to the lead core to hold things together should you strike bone, yet the jacket tapers down toward the nose, allowing for good expansion. That expansion creates a larger wound channel, which destroys more vital tissue and causes death sooner.
MY FIRST FIELD TEST was in Wyoming, where I would be hunting pronghorn antelope. Anyone who has hunted the Great Plains of the American West knows that the wind is always blowing, and sometimes it blows good and hard. I found the antelope I wanted after a couple of hours glassing the prairie, and it required a stalk of just over a mile. I lay prone over a small mound, with cactus everywhere it shouldn’t have been, and settled the crosshairs of my Winchester 70 on the buck’s shoulder 215 yards away. Even through the recoil, I could see that the antelope’s feet drew up to his body as he fell earthward, stone dead, and in that moment, this bullet captured my undivided attention.

The Scirocco II offers good expansion at a wide variety of velocities, and works well in mild cartridges like the .308 Winchester right up to the magnums.

I used it the next spring on a black bear hunt in Quebec. While I knew the shots were going to be inside of 75 yards, as it was a baited hunt, I wanted to see how the bullet would handle the tough shoulder bones of a bear. Canada’s ever-changing weather kept the action slow for the first few days, but a warm-up later in the week drew the bears out like moths to a flame. A 200-plus-pound boar decided to pay a visit to my bait, and I decided to ruin his day. I had loaded the 180-grain Scirocco in my .308 Winchester, to a muzzle velocity of 2,450 fps, and the bullet took him without issue, despite punching through both shoulders. I couldn’t recover either bullet, which was no problem with me, but I was highly impressed with the performance.

Since then, I’ve loaded this bullet in many different cartridges, from the 6.5×55 Swede and 6.5-284 Norma, to the 7mm Remington Ultra Magnum, to many of the .30s including the .308 Winchester and .30-06 Springfield, the .300 Holland and Holland Magnum, and the huge cases like the .300 Remington Ultra Magnum and .30-378 Weatherby Magnum. I’ve even loaded the 210-grain Scirocco in the .338 Winchester Magnum with great results.

The 180-grain .30-caliber polymer-tipped Swift Scirocco IIs make a fantastic all-around big game load.

THE OUTCOME IS USUALLY THE SAME: almost all of the rifles (with the exception of one particularly evil .264 Winchester Magnum) gave subMOA accuracy and excellent field performance. The few bullets we’ve been able to recover from game animals have retained between 80 and 95 percent of their weight, with expansion running right around 2 times to 2.5 times caliber dimension. My wife loves the 150-grain Scirocco II in her .308 Winchester, as it offers less recoil yet great terminal ballistics; her Savage Lady Hunter prints ½-inch groups with this load.

The Scirocco is available in calibers from .224 up to and including .338, and I wouldn’t hesitate to go hunting with this bullet in any situation shy of the truly large and dangerous game that requires a larger bore and heavier bullet. With the Scirocco, between my own hunts and those of friends and colleagues, we have taken animals ranging in size from deer and antelope to caribou to African plains game to elk and moose. Swift only makes two softpoints – the Scirocco and the A-Frame – and that’s one of the best combinations on the market. ASJ

Ready, Set, Load – Part III

 Story and photographs by Bob Shell    
So, if you have been paying attention to Ready, Set, Load parts I and II (found in the American Shooting Journal, May and June 2015), then you have some good-looking rounds assembled. Make sure they feed and chamber cleanly before you leave the shop. Remember, it is easier to fix a problem in your shop than out in the field. Once you have established this basic test, it’s time to shoot, and we will talk about what a well-loaded shot looks like on a target.

First comes safety. If the load is too hot or too light, the signs will be readily apparent. If the rounds are overloaded, it will show most of the time. One mild sign might be a shiny ejector mark on the case head. As a rule they are not dangerous, but it will wear out the brass quicker.

Hot loads wear out a gun more quickly, and except in narrow circumstances, are not necessary. A good example is the 220 Swift. I load mine to about 100 feet per second below the absolute max. The accuracy is great and the groundhogs never notice the difference, but the rifle and brass does. Hot loads will enlarge the primer pocket, which will render it useless; this is not always a reliable indication of excessive pressure, though it should be considered.

Other causes may be a soft primer, sharp firing pin or sticky extraction. If you have a sticky extraction and your chamber is clean and not bulged in any way, you have excessive pressure that is approaching the danger zone, especially in older guns. This is a good time to stop, pull the bullets, check and probably reduce the load.

When you get to the point of blowing primers and excessively hard extractions, then you are courting disaster if you continue to shoot them. The cause could be too much or the wrong type of powder, or even the wrong type of bullets. If you think you put in too much powder, check to make sure you didn’t set your scales wrong when you measured back at the shop. It’s a simple mistake but it happens, which is why it is so important to focus totally on the job at hand. Some of the powder labels look very similar; this is why you should only keep one powder on hand at a time during reloading.

A really light load may leave a bullet in the barrel. If you are not sure if the bullet left the barrel, safely check it out before shooting again. If there is a bullet lodged in the barrel, do not try to shoot it out by pulling the trigger again. This is very dangerous, and at the very least will ruin the barrel.

If the ammo has a different sound every time you shoot, you might have a hangfire, which can also be caused by a load that is too light. What happens is the powder isn’t evenly distributed within the case and does not burn at an instantaneous rate. It will burn slowly or irregularly, hence the hangfire. Old ammo can also cause a hangfire and should be discarded, but you can save the bullet. If you think you have a hangfire, keep the action closed for at least 30 seconds. The powder could also be unstable due to poor storage conditions.

Ammo Accuracy

Naturally, you want to see how accurate your ammo is. Since there are a lot of things that affect accuracy, don’t panic if your ammo is all over the target. Causes may range from loose scope mounts to poor bedding. If you have an accuracy issue, check out everything else first, including the shooter. If the ammo was loaded correctly, then it should be at least fairly accurate. Keep in mind different guns like different loads, so you may have to try a few different combinations to get the accuracy you want.

Using a bullet that isn’t designed for a gun’s rifling is a common mistake. An example would be using a heavy 80- to 100-grain bullet in a .223 rifle with a slow-rifling twist. The bullet won’t stabilize no matter what you do.

If you are able to achieve a 1- to 2-inch minute of angle at 100 yards with a bolt-action rifle, you are right where you need to be. Handguns will vary, but a decent gun and ammo combination should be able to achieve a 3- to 5-inch group at 25 yards, provided the shooter does their part.

So, if you have the desired accuracy and velocity without loads that are too hot, you have arrived. You should keep records of all of your loads, both good and bad. Keeping notes on bad loads should prevent you from repeating them somewhere down the road.

That way you can see and not guess at the velocity, plus you can test it against manufactured ammo of the same bullet weight to see how your ammo stacks up against the factory fodder. Caution! You might get your feelings hurt. Modern factory loads have improved a lot over the last 20 years or so. They are very accurate and consistent and will be as good as custom-loaded ammo; this is especially true with some custom hunting loads.

During the course of my work, I shoot a decent amount of factory ammo and very seldom does it not perform as advertised. The downside to factory-made ammo is the cost, and there may be a problem getting it on a timely basis.

You will get a really great feeling when you have crafted your own product that performs well, rather than having to buy it from a store. Another one of the many advantages to rolling your own is the ability to make ammo for obsolete guns. Shotguns, as well, can benefit from reloaded ammo. I took down a bear with a Lightfield slug that I handloaded. If you take an animal with your loads, this is a special type of satisfaction and there are very few things that will match it. ASJ
