Two Different Barrel Upgrades for the Savage 220
I have lost track (hundreds) of the number of Savage 220 owners I have talked to since November 2016. It has becoming obvious that some OF THE EARLY 220 Savage slug guns; may have lose barrels 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 the diameter of the 20ga Schrifle™ slug. For that reason TarHunt offers a less costly 6-round sample box for testing; 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; NeoTec Copper (green) slug, “The first ever, RIFLE DESIGN, ammo for rifled barrel slug guns”!!!
The 20ga Schrifle™ cannot be made any larger in diameter to match these oversize barrels because the projectiles base is solid copper, with no plastic sabot to compress. It 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 tolerance period!
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 barrel has a slightly heavier wall thickness than the factory barrel and could require a very slight stock inlet adjustment. The #1 replacement barrel is 24 inches long with a 1-24 twist rate. It has muzzle diameter of .870ths at the end of the muzzle brake and adds approximately 1/4 pound in weight to the gun. The barrel is threaded for the Savage action and has a 3″chamber. This 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 $265.00 + shipping If needed, these installation tools will be available and sold as a set. POR
The #1 barrel upgrade installed by TarHunt is: $325.00 plus shipping. Glass bedding the action into a Fiberglass or wooden stocks is $65.00 extra.
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, Premier button rifled, matte finish barrel, Helical Fluting with a 3″chamber. The #2 barrel is a 12ga blank with a 20ga rifled bore; then fluted for weight reduction, strength, and faster cooling . It has a muzzle diameter of .935ths at the end of the Muzzle Brake and adds approximately 3/4 pound in weight to the overall gun. This #2 barrel has a much heavier wall thickness than the standard Savage factory slug barrel and will require a stock inlet adjustment.
This heavier tapered barrel is locked up tight against the action face, using a ground parallel, recoil lug (if needed) in between. It NO longer uses the Savage barrel nut locking system. Locking this heavier wall barrel solidly against the recoil and action face insures the barrel stays tight while it is under the heavy recoil and torque generated by a bore size, slow moving projectile turning at 53,000+ 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+. That’s why this issue of locking the barrel tight to the action must be addressed.
The #2 barrel update (SOLD OUT FOR 2018) is $450.00 Plus shipping . Glass bedding the action into a Fiberglass or wooden stocks is $65.00 extra.
