Down Gauging: The Beretta A-400 Extreme Plus Semi-Automatic 20-Gauge

Estimated reading time: 0 minutes

The Beretta A-400 is an extremely capable shotgun. What follows are is my review, testing and thoughts.

I have shot 12-gauge for most of my life regarding waterfowl.  With the exception of my youth when my father bought me a Beretta model 412, 20 gauge single shot.  That was a great shotgun for a young kid and many a rabbit, duck, and even a goose met its fate with that shotgun.  For lots of reasons, we might consider the downsizing of our waterfowl guns.  I know the obvious is the 20-gauge, but don’t forget the 16, 28-gauge, and 410 as possible weaponry.

Considering Gauge Downsizing

Now, let’s delve into the reasons behind considering gauge downsizing. A medical condition called Atrial Fibrillation (AF) prompts this change for me.  Others may seek a lighter gun, a semi-automatic in a lighter gauge, reduced recoil, or may simply feel they’ve harvested enough and desire a fair challenge, prompting a gauge change.

Aside from being gas recoil, the stock is actually very technical in absorbing recoil.  Overall it does feel softer and kicks less.

For medical reasons, the recoil can be the big player.  Anything from a pacemaker to a recent stint, or by-pass, even back and spine issues or neck problems might instill a desire to keep hunting but with a smaller gauge.  While I continue to shoot a 12-gauge even after my AF and with the doctor’s approval, I often wonder what if I caused something to change simply by the recoil produced with my shotgun.  Making a change to a light gauge, especially semi-automatic gas recoil made sense to me. 

One has to be reminded that many only perceive recoil.  I say that because we assume recoil will occur, but don’t understand exactly how it occurs.  We measure recoil in foot-pounds.  I don’t want to be too detailed here but safe to say that once approaching 25 foot pounds one might start to develop a flinch.  Also note that a side-by-side, over-under, or single-shot gun frame will transmit 100% of the recoil to the shooter, while a semi-automatic in either gas or spring, plus recoil reduction stocks and butt plates will absorb some of the recoil.

Beretta A-400: A Recoil-Friendly Option

Recoil is a nemesis of many shooters no matter the target.  Heavy waterfowl loads are no exception to the kick one feels upon pulling the trigger.  My Browning Wicked Wing 12 gauge (featured here) is gas recoil and has a reasonable kick with heavy loads including 3.5” shells (close to 50 foot-pounds).  Don’t get me wrong it does kick and for some enough to cause concern for many of the reasons listed above.

The Beretta A-400 Extreme in a 20 gauge also gas recoil is slightly less in recoil (say just over 30 foot-pounds).  That reduction is noticed in most loads from light trap and skeet loads to heavy waterfowl loads.  Since we are talking about waterfowl guns the loads are higher and the recoil is increased.  In lighter loads, the recoil tends to lessen and only a slight difference is seen between a 12-gauge and 20-gauge.  Think about what you will shoot most.

The A-400 comes with an additional casting cam plate and drop plate.  You have the option of eight different drop cast options.

Weight, Performance, and Competitive Hunting

The weight is also a benefit albeit a slight.  While I am not comparing two of the same guns I am still confident in saying among semi-automatics, a 20 is less in weight than a 12 gauge.  The Browning weighs in at 7.5 pounds while the Beretta is 6.8 pounds.  Consider some data suggest that weight has an inverse effect on recoil.  Increase the weight of a gun by whatever percentage and an equal reduction in the percentage of recoil will occur.

As a final consideration is the idea that downsizing in gauge will perhaps create a more competitive hunt at least in the eye of the beholder.  For me the challenge is laid down for me to effectively and within the perimeters I have for me personally to harvest with the skill I have in larger gauges.  I love the idea of downsizing so will it stop at the 20-gauge or move to a 28 or even a 410?  My shot selection will of course need to be enhanced, but I tend to shoot over the decoys anyway.  I see this smaller gauge as nothing short of fun.

Getting shells into the magazine is easy and smooth.  The magazine is factory set for two shells, but an additional plug is provided if only one shell is required. 

Final Thoughts on the Beretta A-400

Let’s discuss these shells and accept the fact that a 20-gauge one-ounce waterfowl load contains fewer pellets than a 12-gauge waterfowl load. To consider apples to apples let’s take a look at a 20-gauge #4 shell in 3” vs. a 12-gauge #4 in 3”.  The 20-gauge has approximately 120 pellets, discharging at 1300 feet per second, while a 12-gauge has 134 pellets firing at 1350 feet per second.  About a 10% loss in pellets but reasonably close in velocity. 

In conclusion, using a 20-gauge waterfowl gun instead of a 12-gauge may offer only perceived benefits. My ability to shoot killing shots likely will be all about my skill set and not the gun.  Give the 20s a try and see if you find advantages that meet your needs and do not diminish your harvest rate.

    I once went on a dove hunt on private property and the guy that owned the property came out with us with a .410 pump gun, I believe it was an Ithaca 37, and he came back with more doves than anybody!
    So it’s not about the size of the gun, it’s about the quality and accuracy of the shooter, at least that’s been my 73 year experience! 🧐
