Savage 220 Barrel Upgrades

THE TWO DIFFERENT BARREL UPGRADES are available for the Model 220 SAVAGE SLUG GUN; using either a Blued Steel or Stainless Steel action. Both the #1 and #2 barrels are available, only in Stainless Steel!


SAVAGE 20ga Barrel Upgrades

I have talked to a least thousand Savage 220 owners since November 2016. It has becoming obvious that some OF THE EARLY 220 Savage slug guns may have had lose barrels, a poor fit into their stock, or it may not have a true SAAMI spec barrel. TarHunt premium Savage upgrade barrels are made to the same quality standards as our TarHunt RSG-20ga Mountaineer slug gun. The barrels are Stainless Steel, Match Grade, that was stress relieved two different times during their manufacturing process. They are a SAAMI Spec, button rifled, a 1-24 twist rate, with an integral muzzle brake as standard.

Some Factory Savage 220 slug guns, firing the 20ga NeoTec™ FLC rounds still produce the same size/type of groups as did while testing any typical sabot rounds. That usually means the ID (inside diameter) of the barrel is an inconsistent diameter. Usually in the form of Lose and Tight spots!

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. Both of the 20ga Tarhunt Copper 355gr and 365gr slugs are turned to a diameter of .619ths, exactly in the middle of the (grove diameters), 618ths min. and 620ths max Diameter. The 20ga TarHunt slug fit’s your upgraded rifled barrel exactly like a rifle bullet fits the bore of a match grade center fire rifle barrel.


Upgrade #1: barrel installed is: $410.00,  3″ chamber.

TarHunt has STOPED all DIY sales due to ATF marking requirements and other insurance issues.

TarHunt is offering a SAAMI spec Premier, bore size, Stainless Steel, button rifledmatte finished barrel, with Muzzle Bake. The #1 is a (non-fluted) factory replacement format for the Savage 220. This Premier SS barrel has a slightly heavier wall thickness than the factory barrel and should 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 slightly bigger than a factory barrel at the end of the muzzle brake and adds only about (4) ounces in weight to the slug gun. The #1 barrel has a standard SAAMI 3″ chamber.  


Upgrade #2: barrel installed is: $515.00,  3″ chamber.

The Blued action, Savage 220 shown here is a factory Synthetic Camo stock. It has a #2 Upgrade Fluted barrel installed.  The picture shows both sides of the same Savage slug gun. Scope, rings and bases are not included.


Both the #1 and #2 barrels are a Premier Stainless Steel, Button rifled barrel, matte finish, with a muzzle break as standard. The #2 barrel upgrade has an approximant diameter of .830ths at the muzzle. That is a much bigger muzzle diameter than the standard Savage 220 factory slug barrel. It is a 12ga barrel blank with a 20ga bore and them it was Helical Fluted to reduce some of the extra weight created by the additional wall thickness. It adds approximately 6 ounces in weight to the overall gun. But all the remaining added weight is out in front of the stock; making it more shooter friendly and easier to control. The both replacement barrel have a 3″chamber (1-2twist rate) and is 23/24 inches long and includes a muzzle brake as standard.

Information required send ALONG with the gun.

Include a Hard Copy:  of the above information. Your Driver License and/or Firearm ID card (if you state requires one). The serial number on the slug gun, along with the $100.00 deposit, (check/ MO/cash), made out to TarHunt inside the gun case when you ship the gun.    Email or call me (570-784-6368) before you shipped the weapon, so I know when to be available to sign for it.


Make sure your insurance covers the current replacement costs of the gun, gun case, along with any other items that have prior approval to be shipped. Such as the Telescope, Ring & Bases, etc.

UPS is the preferred shipper as they will deliver the firearm directly to my shop/office for the required signature. 

FedEx, will drop the gun at one of two outside doors and leave. Most times I get an email AFTER they have delivered it and left the area, so I go look for it!   I guess they hope, I was either in the shop, heard them or looking at my emails at that point in time; to find it, before someone else does.

The US Postal Service makes me drive a 28 mile round trip to the USPS office just to sign for the package.    Effective Jan 2022 there will be a $25.00 service charge on firearms shipments thru the USPS.



In compliance with the ATF rules & regulations any firearm maybe shipped to a manufacture for repairs, by its owner.  Once repaired, it is required to be shipped back to the address from where it was shipped from, because that’s where (you) the owner lives. That’s why the copies of you Driver License is required. A “Signature required” fee will apply upon return of the firearm. If you prefer to have an FFL Dealer ship the slug gun to TarHunt: them I must return it to that FFL dealer and you paid him for his service and possible your states sales tax, on the purchase.

I suggest that all shipments of firearms be shipped in a light weight hard gun case with a heavy card board box over the case. Nothing less than card board box inside a second outer box, to protect the firearm. NOTE: any damage occurring, during the incoming shipment or return shipment, without a Hard Gun case covered by a box. Or the use of a second outer box  Anything other than these guide lines, unless authorized by the owner, assuming full responsibility! Because it will be imposable to collect ANY damages from the UPS insurance carrier.   They have shipping requirements for insured firearm packages.  If this requirement is not included during the inbound shipment to TarHunt; you will be billed for compliance with the outgoing insurance requirement when the gun is return.      Note: TarHunt assumes NO reasonability for any shipping damages because the package was not packed according to the UPS guide lines.

Shipping charges will vary, depending on the final weight, box dimensions, value and destination. Our return shipping charge is an estimation only and may be adjusted when your order is shipped. The base price for return shipping of the slug gun is $75.00.   This includes S&H, insurance fees, an outer box required on light weight carry gun case. For the insurance to be in effect when the gun is returned!

Plus any additional over weight, oversize package charges, when a heavy weight gun case was used to ship the gun.   Some (airline approved) Quality gun vaults/cases can weigh as much as twice the weight of the slug gun itself.

IF THE BUILD IS CANCLED BEFORE COMPLETION, THE DEPOSIT IS NON-REFUNDABLE. THE OWNER WILL also THEN BE CHARGED THE RETURN SHPPING COST (not to exceed $100.00) TO BE PAID BEFORE THE GUN IS SHIPPED. This return shipping charge is for the return of a non-completed build, and has NOTHING to do with the $100.00 UP FRONT (non-refundable) deposit for any Stainless Steel barrel upgrade on order.

Liability clause:    It the purchaser has installed one of the number 1 upgrades, (DISCONTINUED “DO It Yourself” barrel upgrades) he/she assumes all responsibility for the proper installation of this number one (do it yourself purchase) barrel upgrade on the Savage 220 bolt action slug gun. This included setting the headspace to the proper SAAMI specification and applying the proper torque on the barrel nut. Once the barrel nut is properly torqued and the head space is rechecked; the purchaser must stamp/mark the barrel with the proper markings as follows (3” 20ga 1-24tr) [along with their initials] in an easily readable position on the barrel. Check the muzzle brake after cleaning the barrel for a bore obstruction, such as a stuck cleaning patch. Check the holes in the muzzle break for carbon/plastic build up every 2 years minimum. There is no implied accuracy guarantee, or implied liability, with any barrel that TarHunt did not install.

NOTE:  TarHunt is not responsible for any and all damages to the firearm(s), person(s) firing the firearm, and/or person(s) as bystanders, due to the improper installation of any barrel that TarHunt did not install. Or due to the failure of the barrel, any type of manufacturing flaw(s) in the Savage 220 action itself, or any failure related to the firing of hand-loaded ammunitions’ or improperly stored ammunition.
