No longer just a slug gun, but not quite a rifle, it’s a Schrifle”

OUTDOOR LIFE MAGAZINE REVIEW:  by COLIN MOORE https://www.outdoorlife.com/blogs/game-changers/shotgun-season-how…

 

TarHunt-Premier “NeoTec” Copper 365gr (green) slug round is the High Performance 20ga Schrifle™ series slug; loaded in both the 2 3/4″ and 3″ standard shot gun hulls. For use in rifled barrels with standard chamber lengths. Order these round by the “length of you slug guns chamber”, period. Performance will be close to equal from one length hull to the other.

 Introducing  the newest 20ga Schrifle series: “NeoTec Copper 365gr” bore size slug. The facts speak for themselves as seen in the accompanying photos below. Look at the real differences between the new the bore size 20ga NeoTec Copper 365gr (62 caliber diameter slug, before it enters the game) and the industry standard 45 caliber sabot projectile. The picture shows the actual REAL difference between a 62 caliber and the 45 caliber slug.  The 26% overall larger diameter of the NeoTec Copper 62 caliber slug vs. a 45 caliber slug is easy to see. The ratio of one to the other remains the same at any magnification.

For comparison purposes this photo shows a 1974 Kennedy .50 cent piece; next to a NeoTec Copper 365gr expanded slug that was fire into a ballistic gelatin block from between 45 and 50 yards away. That range duplicates about 70% of most deer taken with a slug gun. This NeoTec Copper 365gr expanded slug weights 302gr (an 83% weight retention) and it expanded to just over the size of a half a dollar! An expanded slug like the one shown, @1800 fps, and spinning at 54,000 rpm’s (when fired thru a 1-24 twist rate barrel), and weighting over 30 grains, acts just like a hole saw!

“The technology behind the NeoTec Copper 365gr slug”.

The NeoTec 365gr Copper series design is a example of “out of the box thinking .”  The “Hollow Bullet with Internal Structure”, patent number US 9,372,05 B2, uses a pressurized elastomer truss that is flexible enough to alow the thin side walls of the hollow copper slug to upset in size, to better fit your barrel diameter. After firing and the upset to the bore has taken place by the bullet side walls, the pressurized elastomer truss remains strong enough to support the thin copper side walls from collapsing inward while the slug is being forced thru the barrel. Correct implementation of these two events, in that order, is critical to insure proper flight requirements and the elimination of flyers. With this new “hollow bullet” design, a full bore size diameter bullet can be maintained, while greatly reducing its overall weight. Making it possible to load the same physical size bullet at higher velocities than its original full density configuration. [A solid copper bullet of the same size & shape could weigh over 750 grains]. Upon impact, the pressurized elastomer truss it allowed to rapidly expand outward thus aiding in the initial amount of fracturing of the o-jive (pointed part of the slug). The area in the nose section where the wall is the thinnest.

The “hollow bullet” design shown here uses an  full cavity elastomer truss. This design helps generate real expansion of a 99.9% pure copper bullet that will expand and not just shoot thru or implode on impact projectile [Sometime, in the near future, we will be hunting with “HOLLOW  Bullets” supported entirely by internal metal alloy truss. These projectiles will be made on a 3-D metal  printer] at even faster velocities.

The “NeoTec Copper 365gr” Premier Slug

The 365gr NeoTec Copper slug is the newest slug in the TarHunt 20ga Schrifle series. It is a high performance, full expanding, copper slug at 1800fps. It is flying at or near the same velocity as other popular sabot rounds, but it weights a full 100+ grains more!

The all new 20ga Schrifle NeoTec Copper 365 grains at 1800fps will be stable thru all known 20 gauge twist rates. The TarHunt NeoTec Copper slug is a premium full performance, bore size slug, and is on track to be largest diameter, heaviest, fastest, full expanding of all the copper slugs in the industry. While retaining as much as 85% of its original weight when used on thin skin big game. The bore size NeoTec Copper 365gr slug has a unique felt recoil. The slug generates a clock wise torque on the gun and requires two handed gun control, when testing off of a bench rest.

The 20ga NeoTec Copper  slug will also qualify as a “Green” non-toxic projectile for the areas that require a non-toxic slug.  The current trajectory data for the 20ga Schrifle series NeoTec Copper 365gr slug has been added below, next to the Raptor Alv 270gr data, so a side  by side comparison can be made. You may be surprised by the heavier slug. Only a 2″ trajectory arc, either above or below,  your aiming point, thru 150 yards when zero at the proper yardage.


Half Dollar Size Expansion, 82% Weight Retention, Flattest Shooting, More Energy Down Range.

Accuracy Detail

The new 20ga Schrifle series: NeoTec Copper 365gr @1800fps and the Raptor Alv/Lead 270gr @1975fps slug will work thru all known 20ga twist rates. I feel the NeoTec Copper 365gr is by far the best choice for deer hunting with the 20ga Schrifle series of slugs. It is a very accurate slug, when fired in a SAAMI diameter barrel. A non-lead  (a green, non-toxic) maximum expansion slug with a high percentage of weigh retention.


Calculated trajectory: Current indications show the 270gr Raptor Alv/Lead high performance slugs @ 19oo+fps may be the heaviest weight slug usable at those velocities..    Note: the Raptor Alv/Lead 270gr data uses a 150yds zero and the drop looks much better than the 365gr Copper slug at 200yds. But look how high the mid-range trajectory is, using the 270gr**, at 100 yards and it has 15% less energy at 100yds and 17% at 200 yards.

Calculated trajectory:  In  comparing, the 365gr NeoTec Copper @1800fps to 270gr Raptor Alv slug @1975 fps. Notice that the NeoTec 365gr Copper shoots flatter and has more energy at 150yds.. The increased weigh makes it a much better choice for hunting thin skinned big game in the 150 thru the 200 yard range!      

“Why does the 365gr NeoTec Copper slug use a 130yd zero while the 270gr Raptor Alv slug and all brands of sabot ammo, uses a 150 yard zero”?     Notice the trajectory’s number highlighted at 50, 100, 150, and 200 yards.  When using the NeoTec Copper 365gr it means that for the first 150 yards you have a total of a 4 inch maximum variation  in your trajectory curve. In the heat of the battle that means hold center and shoot, no guessing. But look (how low) it is at 200yd. Exactly my point, at 200yds all you have to do it to lay your horizontal cross hair right on top the back bone a squeeze the trigger. The 12″ of drop will place your shot in the heart/lung area.

“No guessing”, EVEN using a scope that has just a standard cross hair.  It’s a quick way of accurately taken shots from 50 thru 200 yards when your using the Premier “Schrifle – NeoTec” slug. No confusion trying to remember which cross hair to use. Along with a slug that has the energy to get the job done at 200yds.

Gel-block video

Look at this you tube video of a 8 inch square, 18 inch long, 21 pound gelatin block, (normally used to test rifle bullets). It was hit with the new, reduced load, 20ga Schrifle slug. The slug is a full bore size 62cal, 260gr. slug fired from a full 40 yards away using a 1-23tr. The lower your twist rate number (1-23tr) the more RPM”S the slug has to aid in cutting a bigger wound channel.

  • Pause
  • Play
  • Mute
  • Unmute

The gel block reacts to the impact of the 20ga “Schrifle” by producing 9-10 different severe shock  waves patterns as the slug moves thru the 17 inches of the gel block! If you look closely you can see the Raptor HP design  separating into 3 peddles, about 120 degrees apart. The peddles then penetrated out ward for Approximately 7 inches.  At the end of the video the 21 pound block is stood up on end and is flipped off the table. The multi-shock waves, seen here in this video, of a 20ga “Schrifle”  moving thru this gel block is a good representation of the wound channel trauma produced by a 20ga “Schrifle” slug going thru a 16″ thick Deer size animal!

 

20ga Schrifle non-sabot slug

UPDATE SEPT 2021

After hearing from a hundred or so hunters, in the last two years, that have tested the TarHunt 365gr Copper slug in their 20ga H&R 960 Single Shot have some good news. They report that the slightly over size bore of the H&R 960 is able to group the TarHunt bore size Copper slug inside 125yards.   It appears that the lighter slug, made of Copper material, is able to get enough grip on the rifling, when fired in a slower 1-35tr, to stabilize the solid/longer bore size projectile. (A 1-35tr is just a little over 1/2 the RPM’S of the normal 20ga 1-24tr.)              I am sure that results will vary from  barrel to barrel, so testing you gun is the only way to find out for sure.

Bad News for H&R 960 Owners

Even though the 20gr Schrifle™ Raptor Alv 270gr and the NeoTec™ Copper 365gr slug will stabilize in the 1-35 twist rate of the H&R; the bore size is still well over the size required to shoot a SAAMI diameter slug with good accuracy.  Actually testing of your barrel is the only way to know for sure. After 50+ years, if I have learned one thing, when it comes to rifled barrels- “there are NO certainties”.

I have conformation, from the H&R gun designer, that H&R 960 20 gauge slug guns were indeed a (1-35tr) and were designed for the old Foster/rifled lead slugs. The barrel bore sizes are very large by today’s SAAMI standards established in 2000. The bore can be as much as a full .007ths bigger diameter (on top of the rifling) than it should be.         Accuracy Note: With that big a bore only the Lightfield Hybred Exp and Commander IDS sabot design can adjust itself to that big a bore diameter, thus maintaining the proper RPM’S for stabilization; because of its patented key-on sabot design.

Randy with all issues about lead slugs, and now they’re going to be banned here in California, and it’s heading that way across the country. There has always been rumors about you guys putting out a copper slug. Just wondering how far away is that from really happening? 

The 20ga Schrifle series slugs are a reality. There is a 20ga Schrifle: Raptor Alv allow slug @1975fps.in 270gr. and the 20ga Schrifle: NeoTec Copper 365gr slug @1800fps.

 

update:
Since then TarHunt has been working a total new slug concept. Patent and trade marked as the  20ga “Schrifle”

It is a bore size non sabot slug round.  This is a full bore size .620ths. diameter 20 gauge (NON SABOT) slug weighing 270 grain.
This event will be even more interesting than it was in 1992; when I introduced the 12 rifle TarHunt Custom Rifle slug gun to the market!
This news should be interesting when it hits the forums…
