The Savage 220Y And The Winchester SX3 Provide Accuracy And Power Where Riﬂed Shotguns Are Needed Or Required
STORY AND PHOTOS BY OLEG VOLK
In modern America, riﬂed shotguns are hybrid creatures spawned mainly by regulatory compliance. Several states require them for deer hunting, with the justiﬁcations ranging from reduced range for densely populated areas to deliberately limited eﬀectiveness to give deer a ﬁghting chance. Their technical provenance, however, goes back quite a bit further.
The ﬁrst bolt-action riﬂe adopted by Prussia in late 1840s, the Dreyse “needle gun”, used projectiles somewhere between 16 gauge and 20 gauge – a 1-ounce bullet riding a paper sabot at around 1,000 feet per second. As riﬂe designs improved and metallic cartridges came into use, several 1870s designs in Europe and the U.S. settled around .44 caliber, with ¾-ounce projectiles launched around 1,500 fps, a velocity suﬃcient to expand soft lead and provide massive stopping power on soft-skinned foes such as humans or leopards. Incidentally, that ballistic envelope is very similar to today’s 20-gauge hunting loads.
As people came upon more thick-skinned game, including Cape buﬀalo and grizzly bears, large-bore riﬂes gained popularity, culminating in the massive .700 Nitro Express. Similar to the 12-gauge shotgun in bore size, the .700 NE had three times the energy and massively greater penetration. Limited to lower-pressure actions, shotguns could not compete.
Big-bore riﬂes, however, had their downside as well. They were very expensive, had massive recoil and launched a day’s wages downrange with every trigger pull. Shotguns, while less powerful, were far cheaper to shoot and didn’t beat up the hunter nearly as badly. For most North American game, whether dangerous or merely edible, 12-gauge slugs were more than suﬃcient at close range.
At distance, some accuracy could be gained with riﬂed chokes or fully riﬂed barrels. As game regulations forced riﬂes out of hunters’ hands in several states, riﬂed shotguns enjoyed a resurgence. A few hunters even chose them over riﬂes for close-range use because of the massive payloads available, up to 2 ounces in 12 gauge. In many areas, the riﬂed shotgun became the working man’s safari riﬂe.
I TESTED TWO EXAMPLES of such hunting arms, the bolt-action Savage 220Y, a lightweight youth 20 gauge, and a Winchester SX3 Cantilever Buck, a gas-operated semiauto 12 gauge. Both have fully riﬂed barrels intended mainly for sabot slugs. In addition to sabot loads, I also tried Brenneke-style slugs, which work in smooth or riﬂed barrels.
The Savage 220Y has no provision for iron sights, so I used it with a 1-4x Vortex scope. With ¾-ounce Brenneke K.O. slugs, it had moderate recoil and gave consistent three-shot groups at ½ inch at 25 yards, the longest distance available to me during the testing. Minimal muzzle ﬂash, good accuracy and respectable terminal performance – around 18 inches of gel penetration with slight expansion to about 0.72 inches – all combine to make it a very viable load for deer or hogs. Best of all, it’s one of the cheapest slugs suitable for riﬂed bores, at under a dollar per round! Rated at 1,475 fps at the muzzle, it comes out just a shade slower from the 22inch tube.
The Savage shotgun also did its part to help accuracy. Its Accutrigger is nice and crisp, and the bolt action was smooth. The only catch was inserting the two-shot box magazine: it has to be pressed against the back of the magazine well to lock in. Single shells may be loaded over an empty magazine through the ejection port.
I then tried 250-grain Hornady FTX and 260 Winchester Dual Bond Elite sabot slugs. Streamlined expanding bullets in plastic sabots have a reputation for accuracy, and both are rated at 1,800 fps muzzle velocity for ﬂat trajectory. With the barrel slightly shorter than the test rig, both were in the low 1,700s from the 220Y, with a pronounced muzzle ﬂash.
With both loads, I was quite surprised by the initial results: a bull’s-eye with each, followed by a hit half an inch oﬀ, followed by a third nearly 2 inches from the initial hole. I reshot the groups with both, and every time they opened up to nearly 7 minutes of angle with just three rounds.
Reading up on the problem, I discovered that sabot slugs shoot straightest from a cold bore. On the return range trip, I was able to shrink the groups by cooling the barrel for a couple of minutes between shots with the bolt open. Both loads shot within 1 inch at 25 yards, reasonable for 100-yard shots on deer, but not living up to the reputation.
With the ﬂatter trajectory oﬀset by decreased accuracy, these looked less useful than the Brennekes, except for one factor: most deer hunting involves one shot on a stationary deer. The ﬁrst-shot accuracy – point of impact corresponding to the point of aim exactly – was excellent with both loads, and the ﬂatter trajectory (about half as much drop at 100 yards compared to Brenneke) makes range estimation less critical.
THE WINCHESTER SX3 comes with a four-shot tube and an optic rail cantilevered oﬀ the barrel. That way, barrels may be swapped and replaced without a substantial shift in the zero. It also had a set of post and notch iron sights visible through the trough in the optic rail.
While adequate, these sights didn’t strike me as ideal, so I put a Holosun red dot on the rail for accuracy testing. I picked it over a larger magniﬁed optic for two reasons: proximity to the bore line and the unlimited eye relief. I wasn’t sure what kind of recoil to expect.
It turns out that my concern was unfounded. The SX3 had no more recoil than the 20-gauge bolt action, thanks to the gas-operated autoloading. The solar-assisted red dot has two reticle options, a plain 2MOA dot and a dot inside 65MOA circle with hash marks for horizontal and vertical reference. That second reticle proved very useful for testing.
Since the main reason to choose a 12 gauge over a 20 is the raw power available, I went with two full-bore loads, Brenneke Green Lightning Short Magnum and DDupleks Monollit 32. Brenneke 1¼-ounce slugs rate at 1,475 fps, but actually recoiled less than the 1⅛-ounce Monolit rated at about 1,400 fps, which suggest the DDupleks load is more optimized for the relatively short 22-inch barrel. In fact, chronograph reports velocity closer to 1,500 fps.
Downrange, Brenneke Green Lightning expands very little, around 5 percent, but has nearly 35 inches of penetration. Combined with a semiwadcutter proﬁle, it is less likely to glance oﬀ such barriers as hog skulls, and that makes it a very viable dangerous-game round.
The Latvian-produced Monolit 32 is a full-machined steel wadcutter supported by plastic driving bands and base. It shows no expansion upon impact and tends to resist deflection by branches and foliage. Gel penetration with it exceeds 40 inches in a straight line. Also, breaking large bones on the way to the vitals will use up quite a bit of the energy.
The two rounds are worthy of each other in terms of accuracy. With just a red dot sight, Brenneke yielded 0.6-inch groups at 25 yards, while Monolit spread 0.67 inches. The groups were extremely consistent and not aﬀected by the barrel heating up. Points of impact moved very little between these two loads, at least at the distance to my backstop.
PLEASE NOTE THAT ALL FIVE loads I tested were short, 2 3/4-inch shells, and both shotguns had 3-inch chambers. To maximize accuracy, you’d want to use 3-inch-long versions, as the projectiles wouldn’t have to jump extra quarter inch of freebore.
I picked the shorter loads to save wear on my shoulder which, in retrospect, turned out to be excessive caution. The recoil from both shotguns was fairly mild.
As a point of caution, the muzzle rise was fairly pronounced with both, so it’s worth holding onto the forend well to avoid a black eye from the scope eyepiece. Using a hasty sling, riﬂe style, provides both the stability for aimed shots and the extra resistance to muzzle rise.
For most meat hunting, the first shot matters the most, and each of these rifled shotguns should provide sufficient accuracy and power out to 100 to 150 yards, depending on the skill of the shooter and the size of the game. For dangerous game, the more powerful 12-gauge autoloader would also provide quicker follow-up shots in case the quarry isn’t alone or the first hit isn’t perfectly placed. For stalking meat game, either would work well, weighing in at around 8 pounds with the respective optical sights. AmSJ
