Zoli Z Trap Unsingle shotgun Trap Gun

The latest Z Series competition shotgun from Zoli is the Z Trap Unsingle shotgun. It features a rib that can be adjusted precisely with a micrometer, either vertically (parallel with the bore), or at an angle to change the point of impact.

The fancy rib gives it a steampunk look.

From the press release …

Antonio Zoli, makers of the Z Series competition guns for Sporting Clays and Skeet, announced the introduction of the long-anticipated Z Trap Unsingle shotgun. Based on the highly successful Z Series action with removable trigger mechanism, the Z Trap Unsingle has an innovative adjustable rib and comb system which allows the shooter to adjust the rib and comb height parallel to the bore as well as change the point of impact. The adjustment of POI with the rib is done via simple micrometer wheels which allow the shooter to raise the pattern over 150%.

The Z Series starts at $5999, I am not sure the Unsingle is available at this price.

    Steampunk alright, but could we have it in 8 bore, Tony?

    • Danford Sawyer

      The maximum bore diameter for Trap is 12 bore.

    I need some help from some of our shotgunning brothers.

    I’ve owned and hunted with shotguns since the early ’70’s, but have never competed in an organized smoothbore event. Mine were used to break a few friendly clays or to put small game on the table. My favorites have also spent their nights bedside as my home defense weapon.The shotgun is a time-honored simple device in my hands, but to a competitor, it seems more specialized than a surgeons tool kit.

    The question that I ask is simple. (I think) How does one define a Trap gun, a Skeet Gun, or a Sporting Clays gun. I see single shots, over and unders, pumps, and semi’s. I also see barrel lengths that are all over the place. Which shotgun is preferable for each discipline, and why? Mind you, the price of the gun isn’t relevant to my question…only the physical traits of the gun itself.

    I appreciate any light that can be shed upon this particular area my dimness.

      The guns for each of the shotgun disciplines you mentioned employ a unique sighting alignment system and ergonomic make-up(weight balance, etc…) that is well suited to each unique type of target presentation.

      For instance the Trap gun shown above is for Singles Trap. The single long barrel with the very elevated sighting rib is designed for the optimal offset needed between line of sight and the intercepting angles required to break a trap target that is rapidly rising and flying away from the shooters. Trap guns also pattern with 80%-90% of the shot(pellets) printing above the direct line of sight. A gun for doubles trap will have the same features but will have the full second barrel.

      Skeet and trap guns usually have more weight to them due to the fact that several hundred rounds could be fired in a given day 100-500++. The physics of the added mass lessens felt recoil. Skeet and trap targets share one thing in common… they are always the same clay target, at the same speeds, at a limited combination of angles. Skeet and trap guns are mostly about making the gun fit you personally so that wherever you look the shot column will follow.

      In the Sporting Clays discipline you will find many more automatics vs O/Us. Sporting clays courses are only limited by the terrain of the course and the imagination of the target setter. Sporting clays use 5 or more different sizes of targets . Sporting clays guns have many performance enhancing features like ported barrels for reduced muzzle climb, many use gas-operated automatics for reduced recoil and fast follow up shots, lengthened forcing cones in the barrel and rapidly interchangeable extended chokes help to tune shot patterns for various sized targets and distances from 10 yds to 60yds+.

      Personally I like the O/U set up for NSCA/sporting clays. I prefer the options of multiple choke configurations and the reliability of knowing my second shot is already in the tube (eliminate the possibility of failure to feed).

      Sporting clays, American or International Skeet and Singles and Doubles Trap are great games. I suggest looking up the various governing orgs for more info and places to shoot.

      NSCA for Sporting Clays
      NSSA for Skeet
      ATA for Trap

      last but not least you mentioned “not” mentioning prices… like most things in life, the “Mercedes-Benz” of shotguns has the price to back up all those features but there are plenty of old men at my shooting club that will hand you your behind on a platter with a gun that embodies more of a “beat up old Ford truck”… By all means get the best gun you can afford, one you enjoy shooting and can be proud of, but practice will win you trophies long before your checkbook will.

      Hope this helps, come shoot our little club in Abilene, TX.

        “…practice will win you trophies long before your checkbook will.”
        That’s a great saying!
        Thanks for sharing the information, helped clear things up for me at least.

        Thank you for your thoughtful reply.

        Your post has given me a much better grasp on sporting shotguns. This is why “gun guys” are often the best people you can meet. We (you) have a willingness to take the time and help somebody else understand their sport.

        Thanks again.

      I’m amazed at the amount of add-ons they can attach to what is basically a tube thru which a load of pellets is randomly thrown!

      I’ve shot both clays and real birds for years now, coming, going away, crossing, rising, and myriad combinations thereof and at all speeds with a simple pump shotgun with a single bead on the end of the barrel, and actually hit them without all the do-dads and whatca-ma-call-its that evidently are required to make these shots.

      Amazing, isn’t it? Almost 30 years now I’ve been doing the impossible!

        Take your gun to the olympics and we’ll see! I’m sure you’re a great shot but once tou get to the top tier you might want to improve every thing that can be improved upon.

    I love benmc68’s response. One other sport to look at is International Trap. I’ve really only seen adjustable ribs at American Trap events. I’m sure they are out there, I just haven’t been exposed yet. I’ve been shooting the same Beretta 391 for 9 years in all the above mentioned sports except International Skeet. I’d really say find a gun that works for you. Kim Rhode has found hers, Harlan Campbell Jr has found his, and those old men have all got theirs. Find it, and stick with it. Try to ignore the “new gun feel,” good luck.

    So this is like the opposite of most rifles… Adjust the barrel instead of adjusting the sights.

    • benmc68

      I guess I don’t follow. I believe that a shotgun/rifle/pistol barrel will deliver it’s projectiles to the same place every time along its ballistic curve. By adjusting a shotgun’s rib (sight plane), or a rifle’s iron or optical sights we are accomplishing the same thing: an interception of line of sight and projectile. The adjustable stocks and sights on target shotguns designated for a special discipline are no different than the rifles we commonly see with specialized adjustments for specialized purposes like the AICS series/ Sako TRG series/ McMillan A2-A5 stocks etc.

      One of the real mysteries with shotgunning is that most non-shotgunners have never seen a what a shot column looks like in flight. Lets say you have an Improved Cylinder/Light Modified choke at 30 yards. Most people understand that it is a cloud of shot 30″-ish in diameter at that distance (viewed as a 2D plane) but very rarely is it discussed that the shot column is 3′ to 5 feet in length (very 3D)and shaped like an elongated diamond. When leading a clay target it isn’t necessarily the width of the pattern so much as it is the length and density of the shot column that breaks targets. Changing chokes (constricting the shot column through narrowing the muzzle’s inside diameter) will effect the density of your pattern and as a rule of thumb chokes are chosen by the distance at which they will deliver a consistent 30″ pattern with a density that will not allow a clay target to pass through the air in the pattern.

      Intercepting angles of sight and projectile is the name of the game in all types of accurate shooting from .22LR to 12ga to .50BMG. Every gun and shooter adapt in some way, sporting shotguns just make it loud and clear.

      Thanks, BM

      An adjustable rib adjusts the rib not the barrel. Adjusting the rib adjusts point of aim exactly like adjusting the sights on a rifle. The difference is that a rifle has a single projectile and has a single point of impact. A shotgun is an area fire weapon that throws multiple projectiles into a “beaten zone” or pattern. In trap the point of aim may be in the center of the beaten zone. We call that a 50/50 pattern. This is the type of patterning generally preferred in skeet and sporting clays and older trap guns. Many shooters prefer a trap gun that shoots high 60/40 or 70/30 etc pattern. With an adjustable rib the area fire or beaten zone or pattern can be adjusted to the tastes and style of the shooter.
      Trap is generally shot at a rising target and a gun that patterns high allows the advantage of the shooter being able to keep the target in sight at all times.

    That’s a pretty clever idea, in a “let’s do this backwards” sort of way. I have to wonder how vibration would affect it.

    Yay, Trapshooting news!

    I thought no one cared about trap other than we select few who have succumbed to the emotionally and financially draining sickness that is trapshooting.

    Keep it coming 🙂
