McMillan Fiberglass Stocks:    is now offering a stock and inlet, (model HTV-M40) for the Savage 220 Slug gun. Call and make sure of a estimated delivery time. It could be 4-6 months under some circumstances.        NOTE: Order this stock with a SOLID FILLED action area for use on a slug gun.

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 20 gauge and one stock for the 12 gauge so they look proper.  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 USE A BOYD’S  STOCK ON YOUR SAVAGE 220; THEN YOU MUST ORDER A BOYD’S STOCKS FOR THE MODEL 220 SAVAGE Slug gun. And then possibility PAY TO HAVE THE BARREL CHANNEL OPENED UP TO THE PROPER DIAMETER TO FIT for a 12ga diameter barrel. Although Boyd’s Stock claim you cannot order a Savage 220 stock inlet-ted with a bigger 12ga diameter barrel channel. I have install at least 10 of them made just that way? Please clarified your order.

NOTE: 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 gun and them buying a Boyd’s  stock separately if your building a custom slug gun.

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 offer lightweight stocks is some models.


More on the Two  Different Barrel Upgrades for the Savage 220:

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, when firing the 20ga Schrifle™ rounds are producing the same size groups as 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 6-round sample box 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 Schrifle series of new slug technology. The NeoTec Copper 365gr is a non-lead slug,   “The first ever, RIFLE DESIGN, ammo for rifled barrel slug guns”!!! 


Accuracy Note:

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! (.618ths min & .620ths max).

The 20ga Schrifle round fired in a 3” chamber will not shoot up to its full accuracy capabilities because of the .750ths+ free bore when fire in a 3″ chamber length. The 2 ¾” chamber shoots much better than the 3” chamber with about .500ths free bore.

2.1” case length of Schrifle chamber is by far the most accurate with the least free bore.  With the Schrifle 2.100ths case length, and 100ths+ free bore. In this chamber length the free bore is controlled by the round having a 2.785ths overall loaded length to function thru clip feed guns.

Either of the two shorter chambers will add $50.00 to the cost of either the #1 or #2 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 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 If needed, these installation tools will be available and sold as a set.  POR

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: $355.00 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 $50.00 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 $90.00.     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.

Since this heavier barrel taper is locked up tight against the recoil lug and action face; a ground recoil lug may be used “if needed” in between barrel and the action face.  The Savage barrel nut locking system will be used on the #2 upgrade due to the inherit design of the 220 Savage action. This heavier barrel will be solidly tighten to place. Insuring the barrel stays tight while it is under the heavy recoil and torque, generated by a heavy bore size projectile turning at 55,000+ rpms. Remember a slug can weight 2-4 times more weight of a rifle projectile. And the actual amount of time the slug spends in the barrel of a slug gun is much longer than rifles at 2650fps and above.         The #2 barrel update with muzzle brake is $455.00  installed.



NOTICE: Prices are subject to change without notice.     As much as a $90.00  charge will be assessed against any original gun work deposits for any cancellations on the owners behalf; to offset return shipping costs of the gun. 

This $90.00 return shipping charge is an assessed fee; for the return of a non-completed slug gun, and has  NOTHING to due with the $100.00 UP FRONT (non-refundable) deposit for the Stainless Steel barrel.

This includes setting the headspace to the proper SAAMI specification and applying the proper torque on the barrel nut.
