Slug Gun Facts Page

Full bore size (non-sabot) Copper slugs & gun control:

The 355gr Copper slug is a premium 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 83% of its original weight when used on thin skin big game. The bore size 3″ 20ga  NeoTec FLC 355gr Copper slug has a unique felt recoil. Because of the weight of a bore size Copper slug, locking directly into the rifling, when it is fired thru a rifled barrel. A clock wise twisting effect is applied to the gun as the slug accelerates from ZERO up to 54,000 rpm’s, as it moves thru the barrel. The effect may go unnoticed by the shooter but the high left flyer always appears on the target if the grip with your left hand was too light!

A firm two hand gun control is required while shooting a slug gun off of a rest. Hold the slug gun the same way you would hold onto a 460 Wby Mag, when firing a 600gr bullet!  Not because the recoil is that Sevier. Because of the amount of TIME the slug spends in the barrel. While constantly trying to twist the slug gun clockwise, before the slug leaves the barrel.   If a high left flyer is your normal flyer impact. It is because to light a hold was used on the gun, particularly with your left hand!     Note:  Your vertical trajectory impact point will also vary a LOT depending on how firm your holding the gun, with your left hand.   See the video elsewhere on the TarHunt web site home page; on Zeroing a Bolt Action slug from a bench.

FYI:  2.2″ Schrifle related

The 2.2″ Schrifle 365gr Copper round is also is also on track for this fall hunting season.

The TarHunt 20ga Copper Schrifle 365gr, the 355gr NeoTec FLC  Copper, and the NeoTec FLC 270gr Alv-lead alloy slug;  will all stabilize in all known 20 gauge twist rates as long as the barrel bore diameter is within  SAAMI specification. 

The “20ga Schrifle” patent “Hollow Bullet with Truss” non-sabot round, typically produces  less than 1% flyers and  retains 85% of it original weight after expanding.  All other current sabot-discarding production rounds average 12% to 15% flyers.

The Schrifle 365gr Copper projectile will not be offered in NeoTec FLC series.

The 20ga Schrifle™ slug must fit the barrel exactly like a rifle bullet fits the bore of a center fire rifle barrel. The 20ga Schrifle™ round was designed to be fired thru a SAAMI spec rifled slug barrel. SAAMI specification for a rifled slug barrel ONLY allows for a .002ths maximum tolerance period! 

The Internal size of a SAAMI specification rifled slug barrel: On top of the rifling (bore diameter) is .609ths minimum and .611ths is the maximum diameters.  In the bottom of the rifling between the lands (grove diameter) is .618ths minimum and .620ths maximum diameter. The 20ga Schrifle Copper 365gr or the NeoTec FLC Copper 355gr projectile is .619ths in diameter, exactly in the middle of the (grove diameters) set at .618ths min. and 620ths maximin diameter.



Wind Drift– Another way of saying slug movement away from your point of aim. It is caused by the wind putting pressure on the projectile while in flight. It pertains to all rifles, slug guns, muzzle loaders and anything that moves thru the air. The effect is more dramatic on slow moving projectiles under 2000fps! It amounts to the “TOTAL AMOUNT OF TIME and the DIRECTION”–the wind has to push on the projectile!”

A head, tail, or cross wind, will affect all posted wind drift and drop figures. Any combination thereof can even move a slug in a diagonal or vertical direction. Head wind or tail wind also has a dramatic effect on the amount of drop seen when firing on an open firing range verses that of actual hunting conditions. With all of these wind drift variables it is obvious that ANY built in flyers (up as high as 12%) cannot be tolerated!

As you can see it ONLY takes a 10MPH cross wind to pretty much double the amount of win drift for each additional 50yds down range with guns under 2000fps. That’s why slug guns and most muzzle loaders CANNOT truly be compared to a rifle. Just by adding 800fps to a rifle round (@2800fps) you will have Aproxamently 75% less drift than a slug gun. That means the rifle will have Aproxamently 4″ of drift, instead of 16″ of drift at 200yds, like the slug gun.

DRIFT @ 50yds +.08″ DRIFT @ 100yds +3.6″

DRIFT @ 150yds +8.4″ DRIFT @ 200yds +15.8″

These wind drift figures are based on a steady (10 mph cross wind). Most people do not NOTICE wind Speed or Direction changes if the wind speed is 10 mph or less without some form of wind direction indicator present. NO wind indicators/flags where you hunt, you are telling me?

Any place I have ever been hunting there is ALWAYS at least one or two (foot high) weeds of some sort, being pushed in some direction by the wind! All you need to do is look for them. Watch them swinging (move one direction and hold it for a few seconds) around on the range while your practicing. You will soon learn what amount of movement gives how much wind drift. On a golf coarse where wind flags are the norm. If you removed the wind flags from a golf coarse there would be all out war back at the club house. Must be because the velocity of golf balls are also under 2000 fps. When you clean up around you favorite deer stand, in Indian Summer, before the season. Tie a few 12 to 16 inch pieces of heavy yarn where they can hang freely in the wind so the deer can get use to them moving. A few weeks before the opening day!

The average wind speed during Nov-Jan (the normal deer hunting season) is 17 to 23 MPH. Guess what the wind drift is at that wind speed? Its “FEET” ! “Considering all of these wind issues; less built in flyers in the ammo is the key to achieving the best down range accuracy when shooting a slug gun around hunting season”. “First eliminate the cause of most of the flyers, (the sabot). Then use a slug that actually fits the bore diameter of a 20 gauge rifled barrel”. “Then and only then can you learn how to shoot a slug gun, at long ranges, in the wind”.


The 62cal/20ga:“NeoTec™ FLC 355gr Copper (just shy of the normal 385gr  7/8oz slug) round will be loader in both the standard length 2 ¾” and 3” 20ga rounds and can be fired in any 3”chamber.                     “Do not fire a 3” round in a 2 ¾” length chamber.”

The 66cal/16ga: The availability of the “NeoTec™ FLC  will strictly depend on the price and availability of the proper diameter copper rod. It will be a 410gr (11/16oz) Copper” slug  will be few grains lighter than the traditional (1oz – 437gr) rifled slug, from years gone by.              The 16ga is only loaded in a 2 3/4″ case.

The 73cal/12ga:  NeoTec™ FLC 500gr (1 1/8oz) weight of the NeoTec FLC Copper bore size slug has been designed to weight the same as normal  trap and sporting clay rounds. And to help hunters to understand that a 500gr slug (1 1/8oz) is NOT a real a heavy weight slug for 12ga guns. The normal (1oz – 437.5gr) bore size 12 gauge rifled slug is a very light slug for the (.730ths ) 12ga bore size. That’s one of the big reasons why accuracy suffers past 50yards in smooth bore barrels. The 12ga NeoTec™ FLC Copper 500gr rounds will be loaded in both 2 ¾” and 3” rounds can fired in any 3”chamber safely.   

Again, “never fire a 3” rounds in a 2 ¾” length  chamber”; just it will fill into the chamber and the action will close and even extract as long as it is not fired!


12ga NeoTec FLC rounds:

TarHunt is planning to release the new 12ga NeoTec FLC slug rounds for this 2022 fall season in both 2 ¾” &  3” chamber lengths, depending on the availably of 3/4″ Copper Rod . The new rounds will be loaded using the TarHunt  patent “Hollow Bullet” design projectile.  [On Hold, due to the current cost of 3/4″ pure Copper rod].

These new rounds will be called the TarHunt 12ga “NeoTec FLC” (full length case) Copper slug , (weight to be determined). They will be loaded in a standard production shot shells, thus eliminating pressure sealing issues in all the various chamber lengths. You will now buy your slugs by the longest length of the chamber, marked on your rifled barrel.


H&R 960 20ga owners   NOW SOME GOOD NEWS

After hearing from a fair number of hunters, in the last two years, that have tested the TarHunt 3″ NeoTec FLC  355gr 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 and the Alv-Lead alloy slug inside 125yards.   It appears that the longer slug, made of a bore size Copper material, is able to get enough grip on the rifling, when fired in a slower 1-35tr, to stabilize the longer bore size projectile. (The H&R 960 1-35tr is just a little over 35,000RPM’S while the NOW normal 20ga 1-24tr spins the slug a just a little over 55,000RPM’S)  I am sure that results will vary from  barrel to barrel, so testing you gun is the only way to find out for sure.

Warning: If a 3” case is fired in a 2 ¾” length chamber; it does not have enough to open to its proper 3” length!




Current loading:    The 270gr Raptor Alv/Lead projectile when fired in ether the, now standard,  1-24tr, or the 0lder 1-35tr. Both twist rates are producing good accuracy out thru 135 yards. But the ft/lbs of energy available at those longer distances is a lot less that the HEAVIER NeoTec FLC 355gr Copper round.

Fact: Of course there are always barrels that seems like they would shoot well, even with rocks, accurately! Some barrels or the action being used with that barrel appeared to be stressed and won’t shoot anything well. If you can tell me what the difference is, we will both become rich, because they always measure the same as other barrels. When this event takes place, change either one, usually changes the results.

Again, “never fire a 3” rounds in a 2 ¾” length  chamber”; just it will fill into the chamber and the action will close and even extract as long as it is not fired!




What is the 20ga “Schrifle”?

The 20ga Schrifle Alv-Lead alloy 270gr @1975fps High Performance non-sabot full bore size slug for rifled barrels. The 20ga Schrifle™ Copper 365gr (green) bore size slug @1800fps is a heavy hitter, max expanding slug with excellent weight retention. The 20ga Schrifle™ non-sabot rounds typically produces less than 1% flyers; compaired to 12%-14% flyers from the other current sabot-discarding production round.

The 20ga Schrifle™ round is the 3rd generation of a hunting slug design and is the ongoing result of over 5 years of research & development. The “out of the box thinking” that culminated into this unique design and was only made possible by the advancements in precision machining from the likes of an iso certified machine shop, plastic development, and new molding techniques. Most importantly, the quality control and consistency of the new gun powders over the last decade has vastly improved.

The 1st generation of sabot slug was developed in the early 1980’s for police use. In the late 1980’s that design was purchased & slightly redesigned by Bob Sowash (the BRI – Company). Then bought out by a shared venture of Winchester & Federal and re-introduced for big game hunting with rifled barrels for the 1991/1992 hunting season.

The 2nd Generation: The slug revolution took place over the next four years, (1993 thru 1996), by the industry in an effort to catch up with the accuracy of the TarHunt RSG-12 slug gun design introduced in 1992. The RSG-12ga would later on would be picked by Field & Stream Magazine (2009) as one of the 50 best guns ever designed, even when compared to the world’s best rifle designs. Even now, after 34 years THCR still remains the “World’s Leader in Slug Guns Accuracy”(1987-2021)”.

The 2nd generation (current production) sabot slug round is a placebo at best; it’s the industries way of giving you “the illusion that rifle like accuracy is available when sabot ammo is fired in rifled barreled slug guns.” Remington introduced the “Accelerator”; a 22cal bullet sabot in a 30-06 and a 30-30 Win case in the 1970’s. That design didn’t work then but the industry when ahead and tried to put ML & Pistol projectiles into the same design sabot for the country’s slug gun hunters anyway. 12% of sabot ammo are flyers using this design.

Ten years ago TH started thinking about all the issues with current sabot type slug ammo the conclusion was that the industry, had pretty much, already exhausted all concepts of using sabot technology developed from the early 1980’s thru 2015. The Lightfield Hybred EXP series using a sabot that is keyed fast to the projectile, still remains the best and most consistent of the current sabot designs.

The “Schrifle”™ design slug is the 3rd generation utilizing a bore size, NON-SABOT hunting slug. This new slug concept uses “out of the box thinking” to correct a number of problems that has plagued the first two generations of sabot slugs since the beginning.

It was decided that the 20 gauge would be best gauge to start with for this “out of the box thinking” attempt to correct the issues with sabot ammo. After 4 years of ongoing research the non-sabot generation, 20ga “Schrifle™” round was released, late in 2015, in an attempt to make an “accurate” short range rifle out of a shot gun. It will take a little time for the 20ga “Schrifle” round to be tried in the wide variety of 20ga rifled barrels configurations that were produced over the last 35+ years. Although, it will stabilize in any known 20ga twist rate. When fired in any of the pre-2000, 20ga RIFLED BARRELS; Accuracy may vary greatly depending on the actual bore size of the barrel.
