TarHunt NeoTec Series of Copper Slug for factory length chambers.  update:  1-9-2021

Due to the loss of the 20ga NeoTec projectile forming dies in a UPS truck fire; the introduction of the 20ga NeoTec 365gr Copper slug round will be delayed. Replacement die just arrived. Check in later on for a more current update.

TarHunt is planning to release, three limited production slug rounds for the 2020 season. A 20ga, and 12ga will be loaded in both 2 ¾” &  3” standard shotgun hulls. The 16ga is a 2 3/4″ round. The 20ga, 16ga and 12ga rounds will all be loaded using a slight deviation of the patent 20ga Schrifle™ bore size Copper slug.   The NeoTec™ Copper slug will be loaded in a standard length production shotgun HULLS; thus eliminating all the issues caused by different chamber lengths in rifled barrel slug guns.

The 2.1” Schrifle™ 365gr 20ga Copper, non-sabot round, is designed for its own chamber length of 2.1 inches. Since is much shorter than any of the other factory length 20ga chambers; there is no conversion to a shorter chamber length is possible without changing the barrel itself. The 2.1” Schrifle™ will shoot reasonable well in a 2 ¾” factory chamber barrel only.   ALTHOUGH PERFECTLY SAFE, FOR BEST ACCURACY, 2 ¾” ROUNDS SHOULD NOT BE USED IN A 3” CHAMBER!

TarHunt will be releasing a new non-sabot NeoTec™ series of Copper (FLC)  slugs. Available in 2 ¾” for the shorter chamber length, and a 3” for the longer chambered barrels. Both the (FLC) Copper 20ga slug and the heavier (FLC) 12ga Copper are non-sabot, bore size slugs and are designed for use in the proper factory length chamber (FLC).

.

The NeoTec series will allow hunters, with standard factory rifled barrels, to access the overall performance of a bore size Copper slug regardless of their chamber length.   The NeoTec™ series of slugs are scheduled for late spring/early summer. As soon as the weather allows range testing for accuracy

Chamber lengths – a major accuracy issue:

When shorter cases are fired in a longer chamber than is required, although completely safe, accuracy and performance will suffer. The slug must jump, unguided with gas erupting all around it because the short case CANNOT seal off the longer chamber. The question then becomes did the slug enter the rifling straight in line or slightly turned off the center line and becomes a flyer? The nose of the slug must squarely enter the rifling to stop from being swaged off center in the bore. The proper length case, related to the chamber length, allows the case to keep the nose of the slug centered entering the rifling, because the straight section of the slug body is still well inside the case.

The major component generating the overall accuracy of the 20ga 2.1″ Schrifle™ is the 365gr Copper (green) projectile. It is the full bore size, non-sabot slug, based on the “Hollow Bullet with Truss”  patent design. A slightly redesigned version of that 20ga Schrifle™ projectile was produced for use with normal factory shotgun hulls and 2 ¾” or 3″ factory chambers.

STOCK NOTES:   McMillan Fiberglass Stocks: is now offering two different stocks for the Savage 220, using either the #1 or #2 barrel upgrade.  The model HTG-M40 is a normal hunting style stock and the A-3 stock leans toward the tactical style stock.  Call for details and make sure ask about a estimated delivery time (623-582-9635). It could be 4-8 months under some circumstances.        NOTE: When ordering either one of these fiberglass stocks, order it with a SOLID GLASS FILLER in the action area.  McMillan now has the proper inlet program for a Savage 220 for either barrel upgrade. Ask for the Savage 220/TarHunt inlet program.

Boyd’s Stocks:    Makes their Laminate stock for the Savage 220 and the Savage 212 slug gun. In either case the stock inlet is cut to the proper diameters for both the factory action diameter and the proper size barrel channel for factory barrels. One stock for the Savage 220 20 gauge and one stock for the Savage 212  12 gauge.  Any questions about this issue, please Call 605-996-5011 before ordering. Boyd’s Gun Stock company has a 90 days return/replacement policy along with a 12% restocking fee.

BE ADVISED:  For those of you who want to upgrade to a BOYD’S  STOCK on your SAVAGE 220; you must order a stock  for a model 220 SAVAGE Slug gun. Once and a while I will need OPENED UP the barrel  on a Savage 220 20ga Boyd’s stock to fit a TarHunt upgrade barrels.  Savage is now offering a 20ga model 220 with a Boyd’s Thumb Hole stock as a factory built slug gun. It should be cheaper than buying a new after market Boyd’s Thumb Hole Boyd’s stock separately.

Note:  For hunters who are thinking about buying a Savage 220  for the up coming 2021 season. Savage has introduced the AccuStock / AccuFit stock for 2021 fall season. It is a new 2021 design synthetic stock called the AccuFit / AccuStock. It has an adjustable length of pull and a comb Height adjustment built into the stock. Colors are Black, Gray and Camo. It is not your normal synthetic gun stock. It has an aluminum bedding block covering over 50% of the entire length of the stocks interior. Impressive synthetic stock upgrade for use on a factory slug gun. The 2021 Sav 220  with the AccuStock stock model is strongly recommended over any previous  Savage models!  The AccuStock stock will not fit any OTHER years of production of the Savage 220 slug gun. I would check it out before buying an older model as it could same you time and money.

NOTE:  A #2 Fluted barrel and the some Boyd’s stock will add a minimum of 1 1/4 pounds to the weight of a factory 220 Savage.   The #2 barrel alone adds 10 ounces to the weight of  a factory 220 Savage. Boyd’s Stock does offer lightweight stocks is some models.

More on the Two Different Barrel Upgrades for the Savage 

I have talked to thousands of Savage 220 owners since November 2016. It has becoming obvious that some OF THE EARLY 220 Savage slug guns may have lose barrels, a poor fit into their stock, or the barrel may not be quite SAAMI spec. Some early  Savage 220 slug guns, with a factory barrel, when firing the 20ga Schrifle™ rounds only produce the same size groups as when using other makes of sabot ammo. When average size groups appears, usually the inside diameter of the barrel is larger than a SAAMI specification for a 20ga diameter barrel.

TarHunt offers a less costly  5 or round  6-round sample box (@ TarHunt discretion) for testing your barrel in  addition to the normal 10-round production box.  Only testing your barrel can tell if your ready to enjoy the 20ga new slug technology. The NeoTec 20ga is a 350gr Copper slug is loaded in 2 3/4″ or 3″ hulls for different length chambers .     “The first ever, RIFLE DESIGN, ammo for rifled barrel slug guns”!!! 

ANY Custom chambers, other than a 3″ length chamber will add $60.00 to the cost of either the #1 or #2 upgrade barrel.

******************************************************************************************************************

Upgrade #1:   TarHunt is offering a SAAMI spec, Stainless Steel, Premier, button rifled, matte finished barrel, in a (non-fluted) factory replacement format for the Savage 220. This SS Premier barrel has a slightly heavier wall thickness than the factory barrel and should  not require very little if any inlet adjustment.  The #1 replacement barrel is 24 inches long with a 1-24 twist rate. It has muzzle diameter of .825ths at the end of the muzzle brake and adds only a few ounces in weight to the gun. The barrel is threaded for the Savage action and has a 3″chamberThis barrel will be set up as a “change it yourself” but it will required access to an Savage Barrel nut Wrench and a 20ga Head Space Gauge

The #1 barrel upgrade cost is $275.00  as a do it yourself configuration.  They are only available with a 3″ Chamber.    Plus shipping

The #1 barrel ( 3″ length chamber) upgrade installed by TarHunt barrel is: $375.00 Plus shipping.

A very limited number of # 1 or #2 barrels with a short chamber may be available. Either in the  Schrifle 2.1 inch chamber or the standard 2 3/4 inch  chamber. Cost is $60.00 extra over  & above the barrel cost.

  Glass bedding a Savage 220 action, fitted with a TarHunt upgrade barrel, into a Wooden Savage 220 replacement stock” is $110.00.     Opening the barrel channel, in a Synthetic or Wooden Savage 220 stock  to fit a #1  or #2  TarHunt upgrade barrel taper barrel is $30.00 extra. A ground recoil lug, if needed, is $32.50. Bedding the action into the factory synthetic stock can be done but it is NOT recommended.

*********************************************************************************************************************

The #2 barrel upgrade installed by TarHunt:  (shown in the Savage picture below and on the home page)

The Savage 220 slug gun shown there has the #2 Upgrade installed.  This #2 replacement barrel is 24 inches long, 1-24 twist rate, Stainless Steel, Heavy Weight Premier button rifled, matte finish barrel, muzzle break, Helical Fluting with a 3″chamber. The #2 barrel is a 12ga tapered blank with a 20ga rifled bore; then fluted for weight reduction, strength, and faster cooling . It has a muzzle diameter of .875ths at the end of the Muzzle Brake and adds approximately 10 ounces in weight to the overall gun. This #2  barrel has a much heavier wall thickness than the standard Savage 220 factory slug barrel but it will fit into the factory stocks. The  220 Boyd’s stock “will require” a barrel channel inlet adjustment because the out side diameter is a 12ga diameter tapper.

The #2 barrel update with muzzle brake is $475.00  installed.

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 NeoTec Copper 365gr projectile is .619ths in diameter, exactly in the middle of the (grove diameters) .618ths min. and 620ths max.
