Definition of a slug gun: “When a slug gun is fired at a shoulder height, (considered to be 5ft above a level plain). The projectile will hit in the dirt at maximum of 250 yards down range”.
“The 20ga NeoTec™ FLC” ( Full Length Case) round is a, lead free, hollow Copper Slug”. The NeoTec FLC round uses the “Hollow Bullet with Truss” patent design and a polymer core, a (Green slug), as the truss. “The last new slug was the all lead “FOSTER Style lead Slug” designed for smooth bores, 86+ years ago”.
Both the 20ga 2 ¾” NeoTec™ FLC and the 20ga 3” NeoTec™ FLC 355gr Copper design slugs are an example of “Out of the Box Thinking.” They must be used in their designated chamber size for “top performance”. Just order you slugs by the longest chamber size marked on your barrel and you will have the right slug for your slug gun! Full information available elsewhere on this web site.

1. Industry standards were 1-34 twist rate used for Foster style lead slugs. This means that the slug rotates one full rotation every 34 inches. After one full year of intense R&D testing (1993) of numerous twist rates including going as far as trying a gain twist barrel which means the slug would start rotating at 1 turn every 100 inches (1-100), at the chamber end of the barrel, and ended up rotating at a rate of 1 turn every 28 inches (1-28) by the muzzle end of the barrel. After all of the testing, we established that a straight 1-28 was the proper twist rate for 90% of all the sabot ammunition used in the 12 gauge bore size. The 1-34 twist was also used as a standard twist rate for the 20ga rifled slug guns. TarHunt was the first US manufacture (1994) to R&D a faster twist rate for 20 gauge rifled slug barrels. The testing clarified that the now standard 1-24 twist rate is correct for a 20 gauge rifled slug barrels.
2. The industry standard at that time was to use porting as a muzzle break system for recoil reduction (i.e. Trap, sporting clays and skeet shotguns). Research and development showed us that a 360 degree muzzle break was more efficient at reducing recoil, stopping muzzle jump and it enhanced the accuracy by creating better separation of the sabots. TarHunt was the first company to offer a muzzle brake as standard.
3. TarHunt was the first production slug gun with a heavy wall (.850ths. diamator at the muzzle) barrel as standard, reducing barrel windup (twisting).
4. TarHunt was the first to use chamber designs and tolerance more suitable for use with rifled barrels and rifle-like accuracy, and not the big as you can make them chambers used in smooth bore hunting barrels so the tooling lasts longer.
5. Find the proper degree of angle for the crown at the muzzle end of the barrel for use with plastic bullet parts and shotgun type powders.
6. Research and development was done to establish the proper stock configuration and stiffness. Why? Because of the length of time that the recoil is present, torque generated and the vertical bounce on the forend caused by shooting medium velocity (under 1800ft/sec.) heavy recoil slugs. The decision was made to use McMillan fiberglass stocks or a wood laminated style. It was determined that the black synthetic stocks now used as the industry standard, because of its price, is not stiff enough for consistent accuracy in slug guns.
7. Standardize the use of a rifle style trigger as well as being able to use after-market custom adjustable triggers without any modifications to the slug gun action.
8. TarHunt was the first to use rifle like, firing pin lock times on a slug gun (Quickness of the firing pin fall until it hits the primer).
9. Quality rifle type action, gun drilled from solid bar stock, not a receiver cut out of a piece of extruded tubing.
10. An action able to mount 90% of available optics using commonly available mounts without gunsmithing.
11. Quality Finishes: Using older style high temperature bluing process instead of the new low temperature blacking process.
12. Custom finishes available by Robar of Phoenix Arizona. Dis-continued 2021
13. TarHunt standardizes glass bedding of the action and a free-floating barrel. This is necessary because of the type of heavy recoil and the inclement weather likely to be encountered during most deer seasons. TarHunt Custom Rifles, Inc. felt way back in 1992 and feel even more here in 2022 that we have the most accurate, best looking and best feeling slug gun rifle in the industry.
From 1993 to the present, TarHunt has sold bolt action slug guns into the domestic, European, African and Japanese markets. With the respect they have garnered in the shooting industry it should also come as no surprise that TarHunt has done consulting work and built research and development of slug guns for every major manufacturer of sabot type shotgun slugs both foreign and domestic.
TarHunt has built guns for Remington, Winchester, Federal, Marlin and some foreign manufactures of slug gun ammo. These slug guns are used in the research and development stages of all sabot ammo developed since 1993. The TarHunt guns are use to set the bench mark for any new product during the accuracy testing stages. Think about it, the sabot ammo revolution started in 1995, two years after we introduced the RSG-12. From 1993 until the present time, all ammo manufactures’ have been trying to catch up with the level of accuray that the TarHunt RSG-12 & RSG-20 can provide.
The TarHunt-Lightfield Ammunition combination has currently passed some production rifle accuracy standards. The Lightfield Hybred EXP and the Commander IDS series of slug hunting ammunition was stopped in 2018.
