Outdoor Life reported an anecdotal Minnesota duck-season comparison using a 20-gauge on opening day and a 12-gauge the next day, followed by plans to pattern loads at a range. The 20-gauge was lighter and produced less felt recoil, while the 12-gauge generally carries more pellets in comparable shot sizes and materials. The test does not establish a controlled lethality verdict, and its selected loads differed in composition and payload.

Outdoor Life reported an informal field test comparing 12- and 20-gauge shotguns for duck hunting, with the hunters using a 20-gauge on Minnesota’s opening day and a 12-gauge on the second day. The comparison highlights the 20-gauge’s lighter weight and lower felt recoil against the 12-gauge’s larger typical shot payload, but it does not establish a controlled finding that one gauge is more lethal.

The report’s author and Outdoor Life multimedia producer Roy Holdford hunted early-season puddle ducks, including teal, wood ducks and mallards, at estimated distances of about 15 to 45 yards. They used two Browning A5 shotguns, each with a 28-inch barrel and modified choke. The author described the 20-gauge version as weighing under six pounds and said some 12-gauge shotguns he had used weighed about eight pounds.

The ammunition was not a like-for-like comparison. The 12-gauge was loaded with Remington Nitro-Steel No. 4 shot and a 1⅜-ounce payload. The 20-gauge used an Apex steel/TSS stacked load of No. 7.5 tungsten super shot and No. 4 steel, with a 1⅛-ounce payload. Outdoor Life said the hunters chose loads they considered effective for each shotgun, then planned range patterning to see whether changing the 20-gauge load could produce performance similar to the 12-gauge.

The report characterizes the hunt as “very unscientific” and says the shooters took notes on their results. Its published material describes the test design and the trade-offs they experienced, but it does not provide a controlled comparison that isolates gauge as the cause of any difference in lethality.

Choosing a Gauge for Marsh Hunting

The comparison matters to duck hunters weighing handling against payload, rather than looking for a simple winner. A lighter shotgun may be easier to keep ready while standing in a marsh, especially when birds approach quickly. Outdoor Life’s author also reported less felt recoil with the 20-gauge, which he said made follow-up shots and movement between targets feel smoother.

Those benefits do not make the smaller gauge automatically preferable. The author said a light gun can be harder to swing smoothly and may feel “whippy,” particularly on crossing shots. Meanwhile, the 12-gauge’s larger shell typically accommodates more pellets when shot size and material are the same. For readers, the practical choice depends on gun fit, shooting skill, conditions and the load used—not the gauge number alone.

Different Loads Shape the Comparison

Outdoor Life framed the test against changes in ammunition availability and cost. The article says denser-than-steel materials, including bismuth and tungsten-based loads, had expanded the options for 20-gauge duck hunters, but that such loads had become scarcer and more expensive. That makes the question of how a 20-gauge performs with available loads relevant to hunters considering a switch.

The report also cautions against treating a 12-gauge as inherently more lethal simply because it is larger. It says pellets of the same material and size traveling at the same velocity have the same lethality, while a 12-gauge shell generally holds a greater total number of pellets. The article cites shotshell expert Tom Roster as saying, “There is little to no ballistic improvement or lethality to be gained by going [with higher velocity].” The point is about the limits of velocity as a shortcut to better performance; it does not resolve how the two different loads used in the field test compare overall.

What the Field Test Cannot Settle

The available report does not provide a controlled, shot-by-shot lethality comparison or establish that gauge alone caused different outcomes. The hunts took place on separate days, and the ammunition differed in payload weight, shot materials and shot sizes. The reported distance range also covers varied situations rather than a single repeatable test condition.

The article says the hunters planned to pattern the shotguns at a range, but the supplied report material does not give the patterning results. It also does not provide enough outcome data here to calculate a success rate or compare performance statistically. The specific question of whether a chosen 20-gauge load can match a particular 12-gauge load at different distances therefore remains unsettled by this field test.

Range Patterns Could Add Evidence

The report’s stated next step was to pattern the guns and assess load selection to see whether a 20-gauge setup could produce downrange performance similar to a 12-gauge. Results from that work would add useful information about these particular guns and loads, though they would not by themselves make the field hunt a controlled lethality trial.

For now, Outdoor Life’s comparison offers a practical account of weight and recoil alongside a reminder that payload matters. Hunters considering a change can use the report as a starting point, while treating its observations as anecdotal and checking performance with the specific shotgun, choke and ammunition they intend to use.

Key Questions

Did the test prove that a 12-gauge is more lethal?

No. Outdoor Life described the field test as unscientific, and its two hunts used different ammunition loads. The report does not establish a controlled lethality result.

What were the main reported advantages of the 20-gauge?

The author said the tested 20-gauge weighed under six pounds and had substantially less felt recoil than the 12-gauge. He said those traits could help keep the gun ready and make follow-up shots feel smoother.

Why might a hunter still prefer a 12-gauge?

With shot size and material held equal, the report says a 12-gauge shell typically carries more pellets. The author also noted that a very light shotgun can be harder to swing steadily on crossing shots.

Were the test loads directly comparable?

No. The 12-gauge used 1⅜ ounces of No. 4 steel shot. The 20-gauge used 1⅛ ounces of a stacked No. 7.5 TSS and No. 4 steel load, so payload and shot composition differed.

What further information did the report say it would seek?

The hunters planned to pattern the shotguns at a range and examine whether a different 20-gauge load could provide downrange performance similar to the 12-gauge. The supplied material does not include those results.
